If it comes to air purifiers, CADR is still king. A score assigned by the Association of Home Appliance Manufacturers, CADR, tells you what size area an air conditioner can purify. We tested looked at ease of replacing filters and features like Auto configurations and air quality detectors and that clean close to 360 square feet. We then talked with air quality specialists and physicians about the significance of True HEPA filters and filters before landing on our two top picks.
High CADR Evaluations
The Association of Home Appliance Manufacturers (AHAM) performs independent evaluations on air purifiers to observe how fast they can remove particles from the air — the clean air delivery rate, or CADR. The higher the CADR numbers, the better. Consumer Reports applicants a CADR score to be”excellent” if it is 350 and above and”bad” if it’s 100 or below. A high number means that the units have stronger fans and bigger HEPA filters to”clean air per hour”
To make it easier for you to find the right quantity of coverage the AHAM uses ratings to figure out. This square footage is tied to Holmes Air Purifiers For Dust per hour (ACH), or how often the unit will cycle through all the air within the room. Most at-home components possess an ACH between six and four, the total recommended by allergists.
In order to cover the majority of rooms, we focused on units that provided the maximum CADR ratings and ACH speeds we can find (which averaged approximately 200 to 300 and four to six, respectively). These units are strong enough to clean close to 360 square feet, which is ideal for homeowners. Nevertheless, we left one model, the Airgle AG500, which had an exorbitant price tag coupled with specs that were mediocre off.
AHAM CADR rating labels are listed on the box of any air purifier; this one is one of our best picks, from the Conway 4-Stage Filtration System.
True HEPA filters are recommended by organizations like the American Academy of Pediatric Allergy and Immunology, the American Lung Association, and the EPA.
These filters force air through a sticky membrane and may capture up to 99.97 percent of particles as small as 0.3 microns. Dr. Petrizzo claims that she”always urges HEPA air purifiers as they are better at trapping small particles like pollens, dander from pets, mold spores, et cetera.”
For testing purposes, a genuine HEPA filter was taken by us.
Three brands fell from the running here. Idylis and sheerAIRE both offered versions that promoted HEPA filtration but demonstrated to have only HEPA-type filters. Blueair, meanwhile, uses a proprietary filter that claims to be better compared to a legitimate HEPA, but we could not find any research to support these claims. Considering that the lawsuits over misleading air purifier asserts at years past we opted for versions with transparent, proven-effective technology.
Pre-filters and secondary filters
To Ensure That the True HEPA filter will last as long as you can, we looked in each of our finalists for two elements:
A pre-filter is a kind of bodyguard for the primary filter. These screens function as a very first line of defense, capturing large airborne particles such as dust and pet hair which would gunk up the main HEPA filter, which is what actually”purifies” the atmosphere. Pre-filters continue for about three months. They’ll need to be replaced or, with lots of models, washed or vacuumed.
Secondary filters add into a unit’s efficiency and can raise the lifespan of the HEPA filter — that the HEPA does not need to work so hard if it has some help. We favored charcoal as a secondary filter, which absorbs clockwise from abandoned a pre-filter, which looks like a window display, a true HEPA filter, and a secondary filter.
Ease of use
With this base standard set up, we brought in all nine remaining contenders for testing. Our two best selections excelled, meeting or exceeding our expectations in each area. The seven systems we considered sometimes had technical specs that are slightly better, but these increases in coverage equaled hundreds of additional dollars upfront for machines which were counterintuitive or bulky to use.

Intuitive controls and detectors
Above all, Winix stands out because of its lineup of attributes. Its completely digital panel lets you control the purifier’s rate or empower PlasmaWave Technology (which, when triggered, claims to”instantly neutralize airborne germs, bacteria, chemical vapors, odors, and gases”). The ease of this digital panel extends into its detectors: The Winix LED lights to shift from the contaminated the atmosphere.
It does not just look the Winix is also packed with features which make life simpler if you don’t need to continuously monitor your own machine. Especially, a built-in air quality detector mechanically runs the fan at its bottom when the air quality is good — a wonderful touch for your peace of mind and for saving electricity. Models such as the Blueair air purifier came with sensors and some controls, but they weren’t nearly as robust as those on the Winix. A breadth of automatic attributes and Straightforward design won us all over.
Popping the hood of this Winix was easy. In contrast, the Conway is much more flimsy, and it requires a few attempts to place the front and pre-filter back after you eliminate them.
Affordable replacement filters
A bonus of this Coway is its replacement filters. One replacement filter for the Conway prices about less than a filter for the Winix, meaning that the Coway averages out to be less expensive than the Winix within a few years’ time. This is a huge win in case you’re worried about economies and want to get the most.
High CADR ratings
The Coway ranks three points greater than the Winix in terms of CADR ratings for dust (even though it’s slightly worse at capturing pollen, coming six points under the Winix). It also notably excels in a number of air exchanges per hour. In the max setting, the Coway averages five air exchanges to get a 360-square-foot room using a nine-foot ceiling — the typical ceiling height of a house. The Winix only averages four and a half air exchanges. While the two numbers exceed the recommendation from our experts, the Conway may be a much better option if you’re looking to take advantage of a room that is large.
Unlike that, the Conway is compact and sleek. It’s somewhat wider than the Winix but overall briefer. Because of this, it’s easy to place the Coway beneath a window. The layout with grey accents, plus feels well-aligned and sleek with the decor. If you value aesthetics, you’ll probably want to choose the Conway within the Winix.
Factors to contemplate
Difficult to change filters
The Coway is more flimsy than the Winix. In our testing, it took a couple of attempts after eliminating them, to substitute front and pre-filter. This is largely due to the fact that the Coway doesn’t have magnets to snap in and out of place; as they perform with the Winix additionally, the filters don’t lock into each other. It’s not a deal breaker, but if you’re carrying it apart every 2 weeks to rinse out the pre-filter (which is suggested for the two units), the Conway is much more of a hassle.
Air purifiers aren’t a buy — your bottom line will affect, especially considering that air purifiers are typically left on constantly. You want to know how many kilowatt-hours your purifier utilizes per day, multiplied by the average electricity rate, to predict your bill.
If you’re searching for an air purifier, make sure it matches your space. As most units function best when they could take in air from all sides air purifiers should not ever be flush against walls or furniture. In case you have a room that is small, ensure your air conditioner is compact enough to fulfill basic requirements.
Consider extra features
The Guardian Technologies Best Air Purifier much more features than you may think. The Winix, for instance, is equipped with features like timers, sensors, and a fan that automatically slows down when air quality is good. You may need when researching air purifiers, consider additional features and consider beyond simply purifying the air in your house. If you are seeking ways to maintain your energy bill low, as an instance, you might opt to seek a purifier having the Auto setting.
