Best Affordable Air Purifier for Allergies

Best Affordable Air Purifier for Allergies – You already know it’s important to regularly clean your home, but there’s one part beyond the surfaces that’s often looked over: the air. Using an air purifier can help make sure the air you breathe is cleaner, but not all air purifiers are created equal.

That’s why the Lab experts at the Good Housekeeping Institute dug deep into the research to find the best air purifiers on the market. We vetted dozens of air purifiers by evaluating their controls and interfaces for ease of use, road testing in our homes and labs, in addition to reviewing specifications and test documentations and selecting from brands we know and trust.


1.Blueair Blue Pure 211+

Our testers have evaluated many Blueair air purifiers in recent years. The brand is a standout for performance and reliability and we found the Blue Pure 211+ Air Purifier to be best for removing an array of particles from the air, including dust and smoke. The device’s three-part filtration system (one each for fabric, particles and carbon particles) claims to clear up to 99% of common airborne pollutants. It’s designed to cover up to 540 square feet, which is the ideal size for a family room, master bedroom or large office.

The best part? You’ll barely notice it working since it’s so quiet. If you’re looking to clear the air in a smaller space, our testers also liked the Blue Pure 411 Auto Air Purifier, basically a smaller, more affordable version of our top pick. 

Pros & Cons

2.LEVOIT Air Purifiers

The combination of value, performance and intelligent design impressed our engineering experts during our Seal evaluation process. In particular, the unit’s three-stage filtration, including HEPA, helps it capture even the smallest airborne pollutants in rooms up to approximately 400 square feet; a built-in precision laser sensor accurately monitors particles in the room and auto-adjusts fan speeds as needed.

The purifier is also incredibly quiet, operating at a whisper-quiet (literally!) 24db, which you’ll appreciate if it’s stationed in your bedroom; one of our staff testers has been running the unit for several months in her home and says the light hum is quite peaceful at night.

Pros & Cons

3.Dyson Pure Cool Link TP02

Using a HEPA filter, this Dyson air purifier claims to clear up to 99.97% of airborne pollutants, including smoke from wildfires, as well as various odors and toxins. Our ease-of-use tests also found a bunch of family-friendly extras on the unit: unlike other fans, it has no accessible blades, so it’s safer for small hands.

There’s also a nighttime mode and a sleep timer as part of its 10 speed settings. You can use the Dyson app to deliver real-time air quality reports that also includes temperature and humidity.

4.Honeywell HPA300

This air purifier from Honeywell, another established brand in the home comfort space, comes in five different sizes that target rooms ranging from small (75 square feet) to extra large (465 square feet).

This model, previously the brand’s largest, claims to clean the air as often as five times an hour and remove up to 99.97% of super tiny airborne particles (including viruses). Since it’s HEPA-certified, our testers found this air purifier to be a superb choice for allergy sufferers because it can remove fine particles and common allergens from the air.

Pros & Cons

5.Coway Airmega AP-1512HH

With an average 4.7-star rating across over more than 10,000 reviews, Amazon customers clearly love this air purifier. Its 4-stage filtration system includes a deodorization layer that’s tough on smells. We like that the model also has an LED light that constantly indicates how clean or dirty the air is.

It’s built to purify the air in up to 361 square feet. In usability tests, our testers gave points for the fact the unit offers various fan speeds, timers and modes to choose from (like an eco mode that claims to automatically save energy when it doesn’t detect air pollution for 30 minutes).

Pros & Cons


Fridababy, a company known for ingenious solutions to everyday parenting problems, recently introduced a small-room air purifier designed for spaces up to 150 square feet—like a baby’s nursery. It’s on our recommended list because, not only is it meant to help filter out dust mites and the like, but it also has a built-in sound machine and nightlight.

We’re all about finding space-saving, multi-purpose products, particularly for our littles! While we have yet to review company testing data on the air purity claims, we found the sound machine and nightly aspects easy to use and the filter easy to replace.

Pros & Cons

7.Molekule Air Pro

Made to work in large spaces up to 600 square feet, the Molekule air purifier pulls in air from every direction, working on a 360 degree spectrum. It’s quiet, portable, and ozone-free. It features a proprietary filter that uses nanotechnology (Photo Electrochemical Oxidation, or PECO) to remove impurities at the molecular level, as well as smart technology, making it compatible with iOS and Android systems for remote operation.

It’s an investment for sure, but Molekule also offers a 30-day trial period, full refunds, and a monthly payment plan. If it makes your life easier, you can also sign up for automatic deliveries of replacement filters (for an additional cost), making this a product you can purchase, plug-in, and forget about.

Pros & Cons


Best Affordable Air Purifier for Allergies – Given the increased focus on air purifiers of late, we decided to update our report with additional model recommendations, based on further specification reviews and road tests of reliable brands. During the pandemic, our chief engineer, Rachel Rothman, tested more than 12 models in her home, logging 100,000-plus hours of total run time, along with extensive usability tests.

The devices were exposed to drying paint, kitchen fumes and even dirty diapers to measure air purification across a range of scenarios and common at-home needs. We also turned to our Lab experts, as well as outside specialists on indoor air quality, for answers to the most frequently asked questions around air purifiers.
