Based on information from the Environmental Protection Agency, most Americans spend 90% of their time indoors. Unfortunately, the amount of pollutants inside is often up to five times higher than most outdoor areas.

Though it’s a worrying statistic, air purifiers can quickly and easily improve the quality of the air inside your home. They may just be your new favorite appliance, especially if you have family members who suffer from asthma, allergies, and other respiratory conditions.

Join us as we show you how to pick the best air purifier for your needs, including our top five product recommendations for 2023.

What To Consider When Purchasing an Air Purifier

Here are some factors you need to consider before investing in an air purifier.


Air purifiers come in different sizes based on the areas they cover: small, medium, and large. But don’t automatically pick the biggest one as size doesn’t determine performance. Instead, consider the square feet area of the room to select a product with adequate coverage.

For example, if your room is under 300 square feet, go with a small air purifying system—preferably one that can cover a slightly bigger area than the size of your room for the best results.


Air purifiers come with different filtering technologies. If you want to ensure clean filtered oxygen, go for HEPA (High-Efficiency Particulate Air) filters. They can remove at least 99.97% of contaminants that are up to 0.3 microns.

Meanwhile, carbon filters are good for trapping kitchen smoke, bad odors, and volatile organic compounds (VOCs). As such, they’re often used with HEPA filters.

Lastly, pay attention to the pre-filter. Ideally, it should be washable so you can conveniently rid them of large particles like dust, dirt, and pet hair while keeping the other filters from getting clogged.

Noise Ratings

You won’t want to use a noisy air purifier. So, choose one that only produces 20 to 50 decibels of noise. This will ensure a peaceful experience, allowing you to use your air purifier at any time.

Clean Air Delivery Rate (CADR) and ACH (Air Change per Hour)

Clean air delivery rate is an indicator of the air purifier’s effectiveness. The higher it is, the more efficient it will be at removing pollutants in the air and circulating fresh air in the room. Note that this factor will vary across room sizes. Ideally, it should be two-thirds of the selected area. So, if you have a 300-square-foot room, you need a purifier with around 200 CADR.

You should also consider the ACH. This measures the number of times that the air in a space is removed and filtered within an hour. Avoid going for anything lower than 4 or it won’t filter the air properly.

5 of the Best Air Purifiers in 2023

If you’re in the market for an air purifier, these options won’t disappoint.

1. Levoit Vital 200S

Levoit Vital 200S is an energy-efficient purifier with a premium 3-stage filtration system that traps airborne contaminants and odors easily even in large spaces.

It has four fan speeds, suitable for different purposes and levels of contamination. But you can always put it on Auto or Sleep mode; the purifier will adjust the speed by itself as you drift off to dreamland, distraction-free and with fresh air in every corner.

Pros Cons

●      The app is easy to use

●      Quiet—even at top speeds

●      Washable pre-filter for removing pet dander and other large particles

●      Doesn’t effectively get rid of odors

2. BlueAir Pure 511

The BlueAir Pure 511 is a small purifier that works quietly—24 decibels on low and 49 decibels on high. It uses HEPASilent technology to capture over 99.97% of airborne particles down to 0.1 microns and is also effective at picking up pollen, mold, dust, and pet dander.

It comes with one filter preinstalled and a pre-filter for easy setup.

Oh, and did we mention it uses less energy than a light bulb?

Pros Cons

●      Sounds like a soft, white noise

●      3 Scandinavian-inspired washable colors to match your decor

●      It can have a short shelf life

●      Filter replacements don’t meet California clean air requirements

3. Coway Airmega AP-1512HH

The Coway Airmega AP-1512HH is a power-packed machine with a 4-stage filtration system that removes more than 99% particulates of 0.3 microns, including VOCs. However, you may want to turn off the “vital ion” filter as it can generate ozone, a known lung irritant.

It also indicates air quality so you can adjust the fan speed to reduce contamination in your room. Our recommendation is to set it to auto mode. It will switch between the three fan speeds available based on the level of contaminants in the space. When the air is clean, it will automatically go into eco mode to save energy and lower your utility bills.

It also has a handy timer feature so you can schedule it to run at specific times.

Pros Cons

●      Adjusts the fan speed based on indoor air quality

●      Has filter replacement indicators for pre-filter and HEPA filters

●      Quiet operation at 24.4-53.8 dB.

●      Limited manufacturer’s warranty — filters are excluded

●      Their customer service could be better

4. CleanForce Rainbow H13 True HEPA Air Purifier

The CleanForce Rainbow H13 True HEPA Air Purifier can provide coverage for up to 2,550 square feet. It has a triple filtration system—a pre-filter, an H13 True HEPA Filter, and an iMACT Activated Carbon Filter. Combined, they trap contaminants like dust, bacteria, and gas molecules from the air and eliminate odors.

Additionally, this product features iLDT micron detection technology so it will detect the level of pollutants in the space and auto-adjust the fan speed. You can also do it manually, keeping it on low to keep noise pollution to a minimum.

The only catch?

It’s bulky. But because it has wheels, it’s easy to transport between rooms.

Pros Cons

●      Has a WiFi-enabled smart app to detect and monitor air purity

●      Color-coded indicators show the amount of pollutants in a space

●      Expensive

●      Tends to randomly stop working

5. Dyson Purifier Humidify+Cool Formaldehyde PH04

The Dyson Purifier Humidify+Cool Formaldehyde is the ultimate choice if you can afford it. It uses Air Multiplier technology to purify and humidify the space while cooling you down. It captures 99.97% of particles that are up to 0.3 microns in size and even removes formaldehyde molecules to keep breathing issues at bay. Because it fully adheres to HEPA H13 standards, the pollutants won’t leak back into the air.

The best part is that it has an app—Dyson Link—which provides detailed reports on air quality, oscillator position, pollution, filter life, and other useful information.

Pros Cons

●      Offers WiFi-enabled app control for monitoring air quality and humidity

●      Eliminates mineral-buildup

●      Has 3 modes: fan, breeze, and backwards airflow.

●      Expensive
