Can an air purifier help with cat allergies?
The United States Environmental Protection Agency (EPA) and the American Lung Association agree that air filtration is a good choice for individuals suffering from allergies and asthma, but an air purifier shouldn’t be the only weapon in your anti-allergy arsenal.
A good air purifier is a powerful part of a complete allergy control program.
Remember, an air purifier is only one part of a multi-tiered allergy control system. Here are some tips to help you to manage cat dander and reduce allergy symptoms.
Choose the right vacuum and clean the floors regularly.
Cat dander can stick to carpets, rugs, and upholstery. Regular vacuuming with the appropriate cleaner can help to minimize your exposure. Select a vacuum with a HEPA filter and well-contained dirt collection area.
Another way to minimize your exposure to dander is by avoiding carpeted floors, which retain fur and dander.

Create a cat-free space.
Because the bedroom is probably the part of your house in which you spend the most time, it’s a good idea for allergy sufferers to prohibit their cats from entering that room. If you can put an air purifier in only one room, choose the bedroom.
Bathe your cat.
Bathing is an effective way to remove dander buildup and saliva on your cat’s body. Using only non-toxic cat shampoo, bathe your cat every four to six weeks.
Once you’ve implemented all of these anti-allergy tactics, consider an air purifier as a final line of defense against airborne allergens from your cat.
Types of Air Purifiers
There are two fundamental types of air purifiers: active purifiers and passive purifiers.
Active purifiers use a variety of methods to sanitize the air by killing airborne bacteria, viruses, germs, and spores. They’re not as effective for capturing allergens.
These purifiers release ions. The ions may be negative, positive, or both, and they work by bonding to molecules in the air and destroying them. They’ve been criticized for their propensity to generate ozone, which is considered an air pollutant and could have serious negative health effects.
Ozone is a powerful natural air sanitizer with the ability to eliminate odors and destroy airborne bacteria, viruses, and mold. Unfortunately, an amount of ozone capable of sanitizing the air is also capable of doing harm when inhaled.
UV lamps can destroy microbial particles including mold spores, bacteria, and viruses. While they’re an effective choice for destroying microbes, only a good filter can capture allergens.
Passive purifiers capture rather than destroy particles. They have a filtration system that prevents particles from continuing to spread through the air. This is the type that will help most with cat allergies.
Homemade Air Purifiers
Air purifiers are available at a wide range of prices. Cheaper models found at big box stores might cost as little as $50, while heavy-duty units may set you back $1000 or more.
A homemade air filter is a low-cost alternative to commercially available units. This video shows you how to assemble a simple homemade air filter using a air conditioner HEPA filter and a standard box fan.
Finding a Great Air Purifier for Cat Allergies: What to Look For
If you’re overwhelmed, ignore all of the other features found in air purifiers and pay attention to a single fundamental component: the filtration system. It’s the key to the purifier’s ability to control airborne allergens.
Look for air purifiers built with a true HEPA filter (high efficiency particulate air filter). HEPA filters capture 99.97% of particles at a size of .3 microns and above. Because of their exceptional ability to arrest airborne particulates, these filters are used to purify the air in medical facilities and cleanrooms. Perhaps most famously, these filters were used in the Manhattan Project to stop the spread of airborne radioactive contaminants.
Some air purifiers feature a filtration system with a “HEPA style filter, “HEPA-like filter”, or “HEPA-type” filter. These filters don’t satisfy the official requirements for a true HEPA filter and may not meet performance standards.
These filters are rated based on how well they block particles of varied sizes. They’re rated according to the “minimum efficiency reporting system” or MERV. HEPA filters are available in a range of MERV ratings from MERV 1 to MERV 12. Higher MERV ratings equate to the ability to remove smaller particles. Filters rated at a MERV 10 or higher are best for arresting allergens.
Unfortunately, most air purifiers don’t publicize the MERV rating of the HEPA filter. You’ll need to largely rely on reviews to make a guess about the effectiveness of the HEPA filter. The quality of the air purifier’s construction also plays a part in how well the HEPA filter captures allergens.
Pre-filters are more porous than the main particle filter. This allows them to capture large particles and prevent them from entering the HEPA filter. A prefilter helps to increase the filtration system’s longevity.
Activated carbon captures chemical vapors in the air, helping to rid the atmosphere of odors. If you’re often bothered by litter box smells, a carbon filter can help to neutralize them, along with other household odors.
Some filters use electrical charges to attract small, light particles in the air. These typically aren’t as effective at capturing allergens, so it’s usually better to use a traditional HEPA filter.
Minimal Ozone Production
Ionizing purifiers, along with dedicated ozone generators, produce ozone.
Ozone is considered an air pollutant by the United States EPA and other government organizations. Breathing it is associated with impaired lung function, chest pain, coughing, and a diminished ability to fight respiratory illness.
Low Operating Costs
Look for an air purifier that has been Energy Star Approved – these are certified energy efficient and will help you to save on the electric bill. Replacement filters also add to the yearly cost of owning an air purifier. Filters range in price, with the highest costing over $100. One way to minimize your operating costs is to choose a unit with a washable pre-filter that can capture large particles before they enter the HEPA filter.
Some air purifiers are loud enough to compete with conversation and relaxation.Look for quiet units with multiple speed settings, allowing you to turn down the volume when you need a quiet space.
Fast and Effective Purification
To control cat allergens, an air purifier should clean an entire room at least six times per hour. Some units tell you how many times they will clean a specific room size per hour. You can also calculate this based on the purifier’s CADR and the size of your room.
The CADR, or clean air delivery rate, is one measure of an air purifier’s ability to effectively eliminate airborne particles. The clean air delivery rate is the number of cubic feet of air the unit will purify per minute.
Some air purifiers have CADR certification granted by the Association of Home Appliance Manufacturers. To attain this certification, manufacturers must subject their air purifier to specific testing procedures that determine the filtering speed and ability to filter dust, tobacco smoke, and pollen.
