how to tell if air purifier is working



Air purifiers are a great way to control your home's air quality. They're convenient, don't take up too much space, and can be used in multiple rooms. However, not all cleaners are created equal! Some cleaners work better than others and some aren't even effective. In this article, we'll look at how you can tell if an air purifier is working by looking at three key metrics: CADR rating, HEPA filter, and AHAM verification (or Energy Star ratings).

Look for the "clean air delivery rate" (CADR)

The CADR rating, or clean air delivery rate, measures how much air the purifier can clean in a single hour. It's also an important measure of efficiency because it shows how much dust and allergens the cleaner can filter out of the air. The higher the CADR rating, the more effectively your purifier will clean your home's air.

Look for a HEPA filter.

You can tell if a HEPA filter is working by looking for it. The most effective air purifier filters are HEPA filters, which remove 99.97% of 0.3-micron particles from the air about 0.0004 inches! They're more expensive than other filters and don't last as long, but they make your home cleaner and safer for everyone.

If you don't see the "HEPA" sticker on your unit, consult an expert before making any purchasing decisions; there are some other types of filters that have similar effectiveness rates to HEPA filters without needing to be replaced as often or costing as much money upfront (but still less than if you had purchased a unit without any filter).

If you do see a "HEPA" sticker on your unit, congratulations: now all you have left to do is connect one end to an outlet near where people spend the most time in their home while using another corded appliance like a TV or speakers with their remote control, so no one needs access)

Check for AHAM verification.

If you want to know if an air purifier is working, look for AHAM verification. The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) is a third-party organization that tests and certifies products such as portable air conditioners and heat pumps. This means that when you see the AHRI logo on the packaging of your product, it's been verified by them to meet certain standards.

Check for Energy Star ratings.

Energy Star is a government-backed program that certifies appliances that are energy efficient. Look for the Energy Star logo on the product, or check its watts per hour (w/h) rating. The higher the Energy Star rating, the more efficient the product is.

You can tell if an air purifier works at optimal levels based on a few key metrics.

To determine if your air purifier is working, looking for a CADR rating is important. CADR stands for Clean Air Delivery Rate, indicating how well an appliance can remove particles from the air. The higher the CADR rating, the more efficient your appliance will be at removing dust, pollen, and other irritants from your home or office.

CADR ratings are typically available on the product packaging or in an instruction manual if you want to research before making a purchase. For example: "This device has a CADR score of 100." This means that it could filter up to 100 cubic feet of air per minute during testing conditions and still meet standards set by AHAM (Association of Home Appliance Manufacturers).

HEPA filters are also important because they help eliminate allergens such as mold spores, dust mites, and pet dander from spaces up to 99 percent of their size when used with an appropriate HVAC system (heating, ventilation, cooling). A HEPA filter may also indicate whether any pollutants have been removed from indoor environments based on the kinds of gases measured during tests conducted by third parties such as UL (Underwriters Laboratories).


Check the HEPA filter and AHAM verification if you're in the market for an air purifier. If these are both verified as working correctly, then there's a good chance that your device is doing its job correctly as well.
