This AHAM Certified HEPA air purifier can cover a larger room up to 1,252 square feet with one air change per hour thanks to the XL fan and the triple-layered filtration system.

But don’t let that fool you about the efficiency rating of this machine!

It is equipped with smart VOC sensor monitors that can periodically inspect the ambient air quality to provide colored-coded feedback and modify the fan speed accordingly. It also provides five fan speeds for only 34-decibel whisper-quiet operation sound, perfect for bedroom.

The filter change light indicator is a practical add-on, too.

Best For Asthma Sufferers: Honeywell HPA300

Like other siblings in Honeywell’s Allergen Plus series, this air purifier is Energy Star labeled and only uses the brand’s exclusive filtration system.

While having the same great function in air-purifying as a typical HEPA filter, the system provides Turbo Clean, which can trap smoke, pet dander, pollen, and dirt to hence help relieve your asthma symptoms and save you from any further asthma attack. Beside this model, we also have other options for air purifiers for asthma sufferers in this article.

Some also-great features are a control panel with touch controls and dimmable lighting plus a programmable timer.

Easy To Clean: HATHASPACE Air Purifier

The HATHASPACE Air Purifier uses H11 HEPA filtration system.

While it is capable of removing 99.5% of the airborne particles as small as 0.1 microns in diameter and not as excellent as the H13 grade (which is up to 99.97%), the overall performance is enough for areas with mild air pollution or people who don't suffer allergies or asthma.

Not saying that H11 HEPA filters are lower in the upfront cost. Particularly with this model, the filters are removable to be cleaned of hair and buildup with ease.

One highlighted add-on that we really like about this model is the remote controller for easy adjustment from a certain distance.

Energy-Efficient: Cuisinart CAP-1000

While most air purifiers that we've tested are only able to pull air from two sides, this model features a four-sided three-layered filtration system for 360-degree air intake, meaning that it provides clean air twice faster than usual.

Along with that, it provides a large coverage up to 1,000 square feet at twice air changes per hour. It also has a child lock and UV-C light.

But what surprised us the most is regardless of the powerful performance, this model works super-efficiently (450 CADR rating) due to the added Night Light function, the 12-hour timer, and Energy Star certified construction. For more tips to reduce your monthly electric bill, check this article.

The Afloia True HEPA Air Purifier can purify 99.99% of 0.1-micron size airborne molecules in a 360-square-foot area within 15 minutes and retain the clean air due to the auto-sensing mode.

That means you don't have to wait that long to get the clean air when using this model.

A very practical feature of the Afloia True HEPA Air Purifier is the lift-up handle positioned at the top so that you can easily move it around with one hand.

The lightweight is also another plus.

How To Choose The Quietest HEPA Air Purifier?

Noise Level

The noise of air purifiers is emitted from the fans, which means the lower the fan speeds, the quieter the unit

The noise ranges of air purifiers are from 17 to 67 decibels (dB). Therein, standard air purifiers work at 36 decibels and an ideally quiet model is at 32 decibels. If you place the unit next to you while sleeping or working, a whispering air purifier at 20 decibels will be your best bet.

But noise is not the sole element when considering an air purifier, performance does matter, too. And, the fans play a huge role in the unit’s functionality. The more powerful the fans, the better the air purifying capability.

To neutralize between operation noise and performance, it is recommended choosing a model with a variety of speed options.

Low speed settings are for sleep, work, or energy-saving while the higher ones are for a shorter cleaning time or higher levels of air pollution.

CADR Rating

CADR stands for Clean Air Delivery Rate, which tells you the efficiency levels of an air purifier at eliminating certain pollutants from the indoor air. So, the higher the CADR rating, the more efficient the unit.

A good CADR rating should be equal to at least 2/3 of the space’s area. HEPA air purifiers commonly achieve the highest CADR rating.

Coverage

Each air purifier is specifically designed to work well in rooms within specific dimensions which are expressed in either cubic foot (cu. Ft.) or square inches (in2).

Picking the wrong model for your space could result in overworking or inefficient, which leads to many consequences like shortened lifespan, steep energy bills, and exposure to harmful airborne molecules.

Larger models generally provide more coverage area than smaller ones, but it’s still recommended checking the coverage area of your intended unit to be certain.
