The Germguardian AC4825 is a budget series air cleaner that has gained popularity in recent times. You can get this purifier for under 100$.
GermGuradian AC4825 ReviewAir Flow
This device is quite durable, keeping in mind that it is build using plastic. The air vents’ location can become a bit of a nuisance when placing them close to corners. This model sucks air inside from the rear and, after cleansing it, outputs it through a front vent. However, you would not want to place it in corners, resulting in less efficiency and decreases air quality.Control Panel
On top of this cleaner, there is a little control panel available to adjust the settings. There are a UV light button, a power button, three fan speed control options, and a filter replacement warning LED light. The filter needs replacement every six months or so if used continuously for 24 hours.Filters
There are three filters in this cleaner. A pre-filter is present, which reduces odors from smoke and blocks large particles. A HEPA filter traps microscopic allergens and dust particles up to 99%, down to 0.3 microns. A UVC light significantly strengthens its ability to kill molds and viruses.Energy Saving
This cleaner is rated at 53 watts, making it fall into the category of energy star. You do not have to deal with massive bills at the year’s end when using this purifier. The recommended room area is 163 sq. feet, making it best suitable for small rooms.Sound Level
However, we found the noise level much louder than other air cleaners, even at the lowest speed. Forty decibels at the lowest rate troubles your sleep, so we do not recommend using this in your room or office.
Moreover, a 30 day return period is available while the warranty goes up to three years.
In our opinion, this is the best air purifier for small rooms. Suppose you are on a constricted budget but want an above-average air cleaner. In that case, we recommend this purifier without a doubt.
3. Levoit LV-H132 – Best Air Purifier for Allergies
Levoit LV-H132 ReviewFeatures
When searching for a feature balanced purifier under $150, the LV-H132 provides you with the bang for the buck. The all-time famous Much to our excitement, the company has included a true HEPA filter in this device, a feature you typically only get to see in higher-end cleaners.Design
Previous models of Levoit usually came in a square-shaped design. With this model, the design resembles much like a cylinder. The pre-filter is present right at the bottom. Air enters from the bottom, passing through multiple filters while finally coming out from the top. You would find basic controls on the top of this air cleaner.
Now coming to the multiple filters on this purifier, let us give you some details about them. The pre-filter acts as a barrier, filtering large particles like dust, pet dander, and mold. This best air purifier has a beneficial True HEPA filter. This filter can reduce up to 99% of viruses, pollen, and bacteria down to 0.3 microns.
We believe the HEPA filter found in this smoker is better than most other companies filters out there. The last filter, an Activated Carbon one, reduces odors and animal smells. This filter is helpful if you have a pet in your home.
Considering it is a certified True HEPA, this cleaner is undoubtedly one of the best air purifiers in 2021. You can buy a new filter at a minimal price of 26$. This price is less when compared with the filters of other companies.
Room coverage and noise level
This device can clean a room measuring up to 129 sq ft. It is suited best for use in small spaces or your bedroom. The LV-H132 would clean at intervals of 30 minutes.
Noise is relatively low, around 36 decibels at the lowest and 50 decibels at the highest speed.
If you ask us, we proudly give this device the title of the quietest air purifier. If you are a sleepyhead looking for something silent and compact, you should consider using this model in your bedroom. Also, this is the best air purifier for the home.
Everybody wants a device that stands out from the rest! The Alen T500 looks like a tower(yes, you heard that right, a tower!). This model is a low-mid budget air cleaner, providing balanced yet rich features.
Alen T500 Review
The T500 sucks air in from the rear; after passing it through the filters, it comes out from the front. LCD controls are on the top with minimal functions. We did not like these buttons since they are a bit hard to press. You have a three-speed fan control, a 12-hour timer. An ionizer present helps the HEPA filter to increase filtration.
Talking about the three-stage filtration system, Alen uses the same system found in other purifiers. The contaminated air first passes through a washable pre-filter. This filter collects large particles like dust, sand, and pet hair. Also, this filter acts as a safeguard for the HEPA filter.
Next, a HEPA filter deals with 99.9% small particles down to 0.3 microns. In the last stage, an ionizer is present to aid the HEPA filter in dealing with pollutants. However, we have not noticed a visible change after turning this ionizer on.
Filter cost and sound level
Another vital thing to note is the air filter cost. A single filter costs around 44$. Keeping in mind, you need to change this filter every six months; you may find it expensive. You can only use this device in a tiny room, not more than 80 sq. ft.
The noise level is loud, even because this purifier does not have a powerful motor. It measures 42 decibels at the lowest, while a crackling 56 decibels sound at higher levels.
We do not recommend you using this air cleaner in your room or a library. However, you may use it in a little washroom or place like this. The loud noise level is a significant disadvantage of buying this device, making this unsuitable for home use.
The Levoit Core 300 has a modern yet simple design, a thing that makes it unique. If you are searching for reliability, the Core 300 does not let you down. It uses a True HEPA filter to filter out particles. This device’s design blends it perfectly into the surroundings, whether it is a room or an office. The build is high-quality plastic.
Levoit Core 300 Review
Touch Control Panel
The device has touch controls on top, although it does not have many features. After connecting it through electricity, the buttons would glow up. You can render it on or off through the control panel, and three-speed fan control is present. There is a sleep mode button too, which reduces the noise and the let’s intensity to our happiness. However, if you still find the light too bright, you can completely diminish it.
You can use this purifier in a large room measuring up to 219 sq. ft, cleaning the air five times in an hour. The three-stage filtration system removes 99% of the pollutants. A warning light starts to glow if the air filter needs replacement. The clean air delivery rate for this is 141 for smoke, 140 for dust, and 145 for pollen.
Allergens and odors get filtered by the primary filter, HEPA filter, and the pre-filter. There is a pet filter present that removes strong odors like pet litter or pungent smells. A toxin absorber filter blocks harmful substances like cigarette smoke, vehicle fumes, and other toxins.
Sound Reducing Technology
A Quite Keep technology found in this best air purifier reduces noise levels to a great extent. A 65 decibels sound level is measured on maximum speed. This much noise level is a little too loud for my liking.
We have found this device to be a very effective one. Quite Keep technology reduces noise levels, which makes sleeping wholesome. You can use this device in a large area like a living room due to its efficient engine. We especially loved the minimalistic design, which blends effortlessly into the surroundings. This is the best air purifier for large rooms.
The Dyson Pure Hot + Cool resembles something from the future. Be mindful of placing it in vintage surroundings, as it does not blend with old furniture and dull colors. However, if you have a modern house with color variations, we bet this device would blend right in.
Dyson Pure Hot + Cool Review
The Dyson Pure Hot+Coolhas more attributes than the average device. For lazy heads like us, we loved how we controlled the air cleaner with a remote. You do not need to get out of your bed to control the fan speed anymore.
Having a thermostat is another life-changing feature you get with this device. It heats your bedroom in chilly winters and cools the area in hot summers. As the world is becoming autonomous, companies have started to automate their purifiers. With the Auto mode present, you do not have to adjust the fan speed or temperature manually. The cleaner takes care of that itself.
There is a Dyson link app available. You can control the power, speed, and other features of this air cleaner even when you are not at home. Air quality monitoring is another useful feature we loved. The 350* rotation purifies the whole room, leaving no room for pollutants.
This device thoroughly satisfies your needs if you plan to use this device in your bedroom at night. A night mode ensures the noise reduces to the lowest, and the light is at the dimmest.
The HEPA filter removes 99% of the various allergens and pollutants. This cleaner has proven itself to be a doctor for asthmatic patients and people with breathing issues.
If you ask us, we consider this the best premium air purifier. The features are countless and are useful in day to day life. The modern design has stolen our hearts, so if you want a feature-rich air cleaner, do not hesitate to choose this one.
Once again, Levoit has impressed us with a classy yet modern design. This air purifier has a matte finish with quite a lot of curves. A yellow light adds to this device’s beauty; when looking for a small purifier that can serve your home or bedroom, be sure to consider this model over others.
Levoit Vista 200 Review
Design and a Universal Adapter:
Design and a Universal Adapter
We have found the design resembles much of the Levoit Core 300 mentioned above. Surprisingly, a 12V AC adapter powers this air cleaner. If you ever misplace this universal adapter, you can get a new one from the market. A cylindrical shape allows the Vista 200 to suck air from all around it.
Energy Saving Filtration System
Let us start with the features you get to see in this popular device. A three-stage filtration system is very efficient. It removes up to 99.7% of dust particles, viruses, bacteria, and pet hair. A minimal 15 watts are consumed, considering this is an energy-efficient device. The increase in your electricity bill is unnoticeable.
Sleep mode takes this device to the next level. Only 26 decibels of sound production, not disturbing your sleep in any way. If the night light disturbs you, turn it off with a mere touch of a button.
3 Stage Filteration
Coming to the filtration stages, a Pre-filter traps material, which usually blocks the True HEPA filter. This pre-filter prolongs the longevity of the primary filter. We highly recommend that you vacuum-clean the pre-filter after a few weeks to remove anything that causes blockage.
The second stage includes the True HEPA filter. This filter captures tiny particles like dust, bacteria, and mites. Furthermore, the company recommends you to substitute the filter. An indicator is present in this device to let you know if the filter needs changing or not.
Activated Carbon at the third stage filters our foul odors and smoke. Smells like cooking, car fumes are eliminated by this filter. This air purifier is for small rooms, not more than 100 sq. ft.
If you ask us, we found no drawback in this device. We love how the manufacturer included a universal and widely available 12V power supply. We call this the best universal air purifier. Also, we have included this in the list of the best air purifiers 2021.
The TaoTronics Hepa air purifier comes in a cylindrical design. It inhales air from the bottom, filters it, and exhales it out from the top. We are not fans of such a design. Although such a design makes it compact, it decreases its efficiency and air circulation. It is one of the best air purifiers in 2021.
Constructed using strong ABS plastic, it has a matte finish giving it a balanced look. The design is well rounded and curvy, making this device safe if you have kids around.
To change the settings, you have four buttons placed right on the top. A light button increases or decreases the intensity of the light according to your liking. This button also acts as a filter replacement warning light. Another button controls the fan’s speed, while there is also a button to activate sleep mode.
Easy to Use
This device is easily detachable. Just remove a few screws, and it gets separated from the middle. You can change the filter easily using this hassle-free method. This air cleaner operates in a 161 sq. ft room with full efficiency. So it quickly filters a mid-sized bedroom or a living room’s air.
Sleep Mode and Sound Level
The sleep mode impresses us. The decibels go down to a mere 25, which is quieter than a human’s whisper. Also, the light turns off, so you sleep like a baby.
4 Speed Fan
A 4 option speed control provides excellent flexibility. You can hear a loud sound at the highest speed. However, you would not hear a single sound operating it at a lower level.
Like other air cleaners, this one also has a three-stage filtration system. A pre-mesh layer is present on the outer side, removing visible particles like animal fur or dust. This filter acts as a barrier to the primary HEPA filter.
The second stage has a HEPA filter, which does most of the work. It removes almost all pollutants, making it dirty in no time. While at the last layer, an activated carbon filter ensures you get a fresh smell.
We adore this device as a bedroom purifier. If you want a compact, easy to open, and efficient device, be sure to make this one a priority. We have given this the best bedroom air purifier’s title due to it having the lowest noise level.
Now air purifier is an essential part of a healthy lifestyle. Moreover, it is our responsibility to provide our body pollutant-free air. For this purpose, good quality air purifiers that featured a thick HEPA filter and real activated carbon filter are the best option.
Natural pure air only exists in the forest, on the sea, or at the top of the mountains. Clean and pure air is the most acceptable gift from nature. Still, we manipulate it badly and convert it into polluted air due to our wrong policies.
In our homes, after proper cleaning, we think our indoor environment is healthy and safe. Unfortunately it a wrong approach, our indoor air is much polluted than outdoor. Sometimes it becomes worst and become 100 times more polluted than outdoor.
Usually, a person can intake 10-12 kg air per day as well as 04-05 kg food and water. You know how much we are curious about our hygiene food and pure water. And what about the air that we intake three times more than food and water? It’s sorry to say, but we neglect this vital element of life is the air we intake clean.
We should think about our environment where we breathe, mostly indoor areas where we spend more than 90% of our time, how to minimize pollutants from indoor air, and maintain a safe and healthy environment to breathe.
The golden rule about indoor air quality is “Prevention is better than cure.” So we need to change our lifestyle. Different methods are used to improve the environment inside the homes, offices, and cars, but the most comfortable and convenient way to use an air purifier. Air cleaners are not only safe to use also economical. Keep reading to explore more about indoor air quality.

- Do you need an air purifier for kitchen activities?
- Do you want to get rid of pet allergens?
- Do you need an air purifier to eliminate odor or tobacco smoke?

- Do you want to breathe clean air during travelling in your car?
Generally, the purpose of an air purifier to clean the air. But for a specific task, some dedicated air purifiers are available and working very well. If you want to deal with PM and pet hairs, you need an air purifier equipped with a HEPA filter. If you want to deal with odor, gases, and radiation, you should go with an activated carbon filter.
Some good quality air purifiers are featured with both HEPA and activated carbon filters. At the same time, some brands offer a washable filter that is economical but less effective. So be clear about the purpose, and then choose the best air purifier 2021.
2- What size air purifier do I need?
In the field of air, purifier weight or dimension doesn’t matter. Here the size of the air purifier is calculated through ACH and CADR rating. First, calculate the area of space where you want to install your device. Air purifiers are also portable; you can move from one room to another.
Anyway, mostly the manufacturer mentions the maximum room capacity in the specification. For better performance, don’t use an air purifier more than its recommended room coverage area.
Read also: What is ACH and CADR rating?
3- Where Should I Put my Air Purifier?
The placement of the air purifier is a crucial point to understand. The performance of your air purifier is based on proper placement. Following points keep in mind for proper placement.
- Keep your device near the source of pollution.
- Do not attach air purifier with walls nor in the corner.
- Put it near the source of ventilation.
- Keep away from other electrical appliances.
- Do not cover your air purifier with cloth or furniture.
4- Coverage Area
Air purifiers available in different sizes like small, medium, large, or a whole house. Now explore in which room you spend your maximum time? Or which room is more polluted? Like a pet’s room, kitchen, or smoking area. After that, calculate is the area (length x width) i.e.
If your room size is 20 x 16 feet
The area of the room is 320 square feet.
So you need an air purifier covering an area of more than 320 square feet like Tao Tronics TT-AP002.
5- Air Change per Hour
An air purifier’s performance based on ACH (air change per hour) means how much time your air purifier recycles the air in one hour. As we mentioned above, the room with 320 ft2 and the same model TT-AP002 can purify 330 ft2 every 15 minutes.
So the ACH of Tao Tronics TT-AP002 air purifier is 04 for a room of 320 ft2 area.
6- CADR Rating
The main factor that calculates the ultimate performance of an air purifier. CADR (clean air delivery rate) rating is calculated for dust, pollen, and smoke. Another term CFM use in an air purifier, which is used to measure airflow. But the CADR is a different thing; it means how much air is cleaning during flow.
For example, suppose your device’s airflow is 300 CFM, and its CADR rating is 150 CFM. In that case, it means your air purifier only purifies half of the passing air. Now the question comes to mind, what is the best CADR rating? So the golden rule is 2/3 means the CADR rating of your air purifier should be 2/3 of its airflow.
7- Filters Replacement Cost
An air purifier is not a significant investment; mostly, mid-size air purifiers available at a very affordable price. But they are not a one-time investment. They have some extra running costs instead of electricity. That is the filter replacement cost, which is an essential factor to consider before buying an air purifier.
There is no specific time to replace a filter; it is based on how much time you run or the air concentration. Some smart air purifiers featured automatic sensors indicating the filter replacement, while some have to check manually.
Some air purifiers are equipped with a washable filter as well as a pre-filter. That increases the life of the secondary filter. So always prefer a quality product with low filter replacement cost.
8- Smart Features
We live in the modern era, now manual work replaced by automatic features or artificial intelligence. Latest air purifiers are also equipped with smart features that provide us with ease of use and more accuracy. Smart features like auto mode, smart sensors, voice assistant, filter replacement indicator, Wi-Fi, and android app let you monitor and control your air purifier.
With these high-tech upgrades, you can also fix a cleaning schedule as per days and hours. As well as the auto mode is also helpful to reduce running cost.
9- Noise Level
Along with other factors, the decibel level is also essential. Usually, portable air purifiers are noisy, but some good quality air purifiers are working on low noise levels even at high speed. Let’s understand the noise level; you can estimate that our average conversation decibel level is = 60 dB (A).
Portable air purifiers are mostly placed in our living room or bedroom, and a high decibel level is a headache. We mention below the air purifier categories according to their noise level.
- Extremely quiet air purifier = 15 dB(A)
- Best air purifier (Whispering) = 20 dB(A)
- Good air purifier = 32 dB(A)
- Standard air purifier = 36 dB(A)
Above 36 dB(A) air purifiers are not suitable for indoor areas. You have to choose the right product for a low decibel level of noise.
10- Power Consumption
According to ENERGY STAR, the average size air purifier consumes 45-50 kilowatt-hour per month that is not a big deal. If you are curious about power consumption, always choose appliances having an energy star label. Typically air purifiers are energy efficient as compared to other appliances. But choose an energy star air purifier. You can reduce your power consumption by around 18-20 Kilowatt-hour per month.

The extended warranty period shows the durability of the product and the credibility of the manufacturer. It shows how confident a manufacturer about his product. An air purifier is not a complicated device; it is simple and contains only a few parts and mostly long-lasting products. However, always ask about warranty and customer support from the manufacturer.
