How to Buy an Air Purifier

Air purifiers are popular today owing to the Coronavirus pandemic and concerns over air pollution. The fact they can filter out particles carrying the Covid-19 virus makes them a must-have in many households. However, with so many brands, it begs the question; how do you choose the best air purifiers?

Here are the vital aspects of choosing an air purifier.

Choose an Air Purifier According to the Room Size

It’s essential to figure out how much space you want the air purifier to clean. For example, a small desktop device is enough for a kid’s bedroom, while a heavy-duty purifier will do a good job in a large living room or office.

To this end, you may want to learn about “air changes per hour.” Air purifiers have this rating to indicate how capable it is of cleaning air according to the room size. An air purifier that can turn over air eight times an hour in a 350 sq. ft area will only be effective in a 700-sq. Ft room since it can only turn over air four times an hour. The EPA recommends having an air purifier run air in a space five times an hour.

While air turnover is a good guideline, it’s also good to look at the Clean Air Delivery Rate (CADR) for pollen, smoke, and dust. This rate tells you how quickly the unit can remove 100% of a pollutant from a cubic foot of air per minute. It is independent of the room size; hence you can check for a higher rating indicating it can purify a large space or change air more times per hour.

Consider the Type of Pollutants the Air Purifier Filters

There are different types of indoor air pollutants. With Americans spending 90% of their time indoors, it’s important to address your indoor air quality effectively. Thus, you will want to consider a unit that can filter the type of pollutants in your home. If you have pets, you’ll benefit from a device designed for pet hair and not for smoke.

Type of Filter Used in the Air Purifier

All home air purifiers use an air filter to clean the air. Air filters are ideal because they are regulated, unlike other air purification methods that use ultraviolet light or ionization. The gold standard in the US is HEPA filters because they use ultrafine fibers to trap particles. Certified HEPA filters can trap 99.97% of 0.3-micron size particles. These include the particulate matter in smoke and volatile compounds in things like paint, pesticides, cleaners, etc. HEPA filters can trap large particles like pollen, dust, and mold spores. You’ll want a model labeled as a True HEPA filter since it’s been certified, unlike units with HEPA-like or HEPA-type designation.

However, HEPA filters do not remove gases. That’s why air purifiers also include an activated carbon filter to remove toxic gases and odors. If you’re worried about paint fumes or odors from the smoke, it’s a good idea to have an air purifier with an activated carbon filter.

Still, there are air purifiers that also include negative ion generators and ultra-violet light. These are usually more expensive, and you can only know their effectiveness with universal testing standards.


Since air purifiers need to run regularly, you’ll need to consider the noise level in decibels. Air purifiers can run quietly with noise ratings as low as 17 dB, fainter than leaves rustling, and as loud as 60 dB, similar to a humming refrigerator. If placing an air purifier in a child’s room, it’s best to go for one with relatively low noise, even at the highest setting. Also, go for something other than the largest air purifier, as it is likely too loud, and you will keep turning it off to have a conversation.

Energy Efficiency

Again, an air purifier will run all the time or regularly. Therefore, it’s best to choose a model that will keep energy use at a minimum. You’ll want an energy-star-rated device since it is more energy-efficient than other models.

Other Features

Apart from the above considerations, you’ll benefit from an air filter with features such as a pre-filter to catch large particles, such as pet hair, before it reaches the HEPA filter and activated carbon filter. This prolongs the usefulness of the expensive filters since you can remove the pre-filter, wash it, and reuse it.

Other features include inbuilt air-quality monitors, filter service indicator lights, carrying handles or wheels, and remote controllers.

Improve your overall health by breathing clean air. The Coway Airmega AP-1512HH can reduce airborne allergens and pollutants. It’s robustly engineered and powerful enough to clean air in small and medium-sized rooms. For these reasons, it’s the best air purifier for most people.

Honorable Mentions

While we loved the models on our list, we checked out more air purifiers on the market and found more worth mentioning.

BLUEAIR Blue 411 Bedroom Air Purifier: This device uses a True HEPA filter and can clean air in rooms of 161 sq. ft. It also operates silently at 17dB. However, it does not have an eco or auto mode, so you need to turn it off when you want to preserve energy.

BLUEAIR Blue 311 Air Purifier: This air purifier works hard to remove allergens in rooms up to 388 sq. ft. Nonetheless, it does not indicate the setting it’s on, so it can be a while before you understand the settings.

Alen 75i Air Purifier: This model is ideal for homes and offices up to 1,300 sq. ft. It uses a True HEPA filter and only produces 25dB noise when operating. We, however, don’t like that its auto feature does not work efficiently to ramp up the fan speed up and down as needed.

ORANSI Air Purifiers: A sleek unit that can purify the air in large rooms up to 1,312 sq. ft. The fan is also quiet. Still, it would be great if the build quality is sturdier to improve its durability.

Coway Airmega 250: This air purifier uses a True HEPA filter to clean air in rooms up to 930 sq. ft. It’s also silent since the loudest hum is only 22 dB. The app is the part we don’t like since it takes several tries to register the unit and log in to the app.

Coway Airmega 200M: This is a fantastic option for neutralizing cigarette smoke and other airborne allergens in living and family rooms. You won’t like it in a big space like a studio apartment since its highest fan speed is a bit loud.

Winix Air Purifier with PlasmaWave Technology: Winix has a room coverage of 360 sq. ft. Its True HEPA filter has a minimum noise level of 27 dB. Nevertheless, its peers are cheaper, and it runs louder than them. Also, the air filter replacement cost is higher than the competition.

Winix AM90 Wi-Fi Air Purifier:  While this unit can clean air in medium-sized rooms up to 360 sq. ft, the connectivity is an issue when you try to connect it the first time. Some people suggest turning off your mobile data before trying to connect it.

Sans HEPA 13 Air Purifier: This is an incredible air purifier for large rooms of size 1500 sq. ft. Since it uses an ordinary HEPA, not True HEPA filter, it’s not the best choice for preventing dust.

Bulex Air Purifier with H13 True HEPA Filter: Bulex can clean air in large rooms from 404 sq. ft. to 808 sq. ft. However, it needs replacement filters after a few months, usually four months for most people.

My Happi Air Purifier in Black: A 5-filter technology, including a True HEPA filter, allows this unit to cover small rooms of up to 150 sq. ft. The device does not come with instructions; hence using it is more complex than it should be.

LEVOIT Air Purifier H13 True HEPA Filter: This device works great to clean air in a 129 sq. ft room. Its noise output is only 25dB, so you’ll barely hear it running. Since it’s a portable air purifier that will need moving from room to room, the bottom cover falls off when you lift it, which can be annoying.
