How Do You Choose The Best Air Purifiers For Cat Litter Dust?
Respirable cat litter dust measures less than 10 microns in diameter. In terms of air purification, those are big particles—easy pickings for any top-of-the-line air purifier.
The best purifiers are outfitted with HEPA filters, which capture 99.97% of .3 microns and above.
The best HEPA filters capture particles as tiny as cat dander and radioactive contaminants, but such a top-level HEPA filter isn’t necessary for dust alone. In fact, much of your cat litter dust won’t make it there. Instead, the pre-filter will catch it before it reaches the less-porous, more expensive primary filter.
If you’re looking to control dust alone, an ultra-fine filter may not be necessary. Anyone who wants to capture bacteria, smoke, and dander, however, should look for a purifier with a good HEPA filter.
The best air purifiers for cat litter dust have a high CADR (clean air delivery rate).
A fast purifier will clean an entire room six or more times per hour, keeping the air fresh all day and night. But since rooms vary in size, we need a standard rate by which we can compare various air purifiers. That’s where the CADR comes in.
This value represents the number of cubic feet the air purifier cleans every minute. Your numbers will differ based on which types of pollutants are present in the air. While there’s no way of knowing how the purifier will handle your air composition, it helps to look for CADR numbers specific to different pollutants.
To help you get a clearer idea of the purifier’s efficacy, AHAM (the Association of Home Appliance Manufacturers) releases CADR numbers specific to various pollutants. Products are tested for their ability to purify tobacco smoke, pollen, and dust.
The best air purifiers for cat litter dust aren’t just fast. They’re energy-efficient, too.
Air purifiers span the price spectrum, with some costing less than a bag of (fancy) cat food and others going for $800 or more. What you pay upfront matters, but you’ll also want to think about operating costs. Look for air purifiers that are Energy Star certified for energy efficiency and which feature multiple filters to extend the longevity of each.
Look for purifiers that excel in odor neutralizing.
The best air purifiers tackle both dust and odors. Look for units that contain a prefilter to capture large particles, a secondary filter to capture smaller particles, and a carbon filter or other odor-neutralizing filter.
