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.

  • CADR: AHAM certified for 350 cubic feet per minute
  • Key Strengths: An all-around high-performance air purifier
  • Ideal For: People who want a well-rounded, mid-range air purifier
Pros
  • One of the most aesthetically-pleasing air purifiers on the market
  • Has a triple filtration system for a complete clean
  • Energy-efficient and cost-effective
  • Simple one-button operation
  • A quiet, unobtrusive air purifier
Cons
  • Cat litter dust and other larger particles will visibly gather on the external prefilter
  • Doesn’t have a true HEPA filter—not a good option for people with severe allergies and sensitivities
  • Some reviewers say that the air purifier produces a bad smell when it’s new
The Blue Pure 211+ air purifier is a mid-priced, mid-sized unit that works well in homes of almost any size. It’s AHAM certified to filter air five times per hour in rooms measuring up to 540 square feet.

It has a three-level filtration system featuring a washable fabric prefilter, a particle filter for smaller particles like allergens, mold, and other irritants, and finally, a carbon filter to neutralize odors.

Though the particle filter falls just short of HEPA requirements, most users won’t notice much of a difference. Customer reviews say that the purifier handles everything they throw at it, from “stinky stagnant air” to dust and pollen.

Though it’s not the cheapest air purifier you can buy—at $295, it’s right around the middle of the price spectrum—this air purifier is an efficient investment. It’s Energy Star rated for best-in-class energy efficiency. A washable prefilter cuts down on your replacement costs.

One of this air purifier’s biggest selling points is its appearance. With multiple prefilter colors and a boxy, Apple-esque design, this is a refreshing switch from air purifiers that look like they belong in a hospital. One reviewer even went so far as to suggest that this air purifier might earn you a few friends. Tips650 says that “once you pull this baby out of the box, you’ll instantly transcend to ‘the guy with the cool air purifier’.”

The bulk of negative reviews revolve around the air purifier’s tendency to produce an intense plastic smell when it’s new.

  • Energy Star Certified for energy efficiency

  • Compatible with a variety of replacement filters geared towards specific needs
Cons
  • Some reviewers say that the purifier puts off a plastic smell when it’s new
This AHAM-certified air purifier uses Vortexair Technology to create a forceful airflow and is certified to circulate air 5 times in a 215-square foot room, ensuring that the air remains continuously clean.

The unit has a three-filter system that includes an ultra-fine prefilter, which will capture larger particles of cat litter dust, a true HEPA filter rated to capture 99.97% of particles as small as 0.3 microns in size.

At just under $100, it’s one of the cheaper purifiers you can buy and, in addition to its low up-front cost, the purifier has several features for greater efficiency and cost-effectiveness. The air purifier is Energy Star Certified and designed for longevity, with an “excellent internal structure” that “increases abrasion resist”. With 2, 4, 6, and 8-hour timers, you’re able to control how long the air purifier runs—another life-extending feature.

Though the purifier comes standard with Levoit’s original filter, customers can replace it with specialized filters for pet allergies, toxins, and mold and bacteria.

Reviewers say that it’s attractive, compact enough to put almost anywhere, and noticeably freshens the air. While most customer reviews are positive, this purifier isn’t exempt from complaints.

The number one problem mentioned in negative reviews was the unit’s smell. Numerous reviewers were disappointed by the purifier’s tendency to put off an intense plastic smell during the first few hours of operation.

In addition to being one of the cheapest air purifiers you can buy, it’s an economical long-term investment. Instead of replacing it every few months, you’ll vacuum the particle filter to remove accumulated dust.
