According to a recent industry survey, 67 percent of American households—85 million families—have a pet. Unfortunately, these furry and feathered family members can contribute a lot of dander and unpleasant odors to the home. Dander is composed of the tiny, often microscopic, flecks of skin that nearly all pets (cats, dogs, birds, and rodents) constantly shed.

If not regularly cleaned, dander may cause allergic reactions in people who specifically have these triggers. Air purifiers can help reduce or even eliminate those side effects of pet ownership. In this guide, we enlist expert advice to single out the best air purifiers on the market for pet owners along with everything to keep in mind when shopping for these devices.

How We Chose the Best Air Purifiers for Pets

The right air purifier can cleanse air pollution caused by pet odors, dander, and kitty litter. We selected each of our top picks for their effectiveness, size, noise level, and user-friendliness. But above all, we paid close attention to the filtration.

According to Micah Sherman, a Frontdoor virtual HVAC expert, the best air purifiers for homes with pets come equipped with high-efficiency particulate air (HEPA) filters. “They are the gold standard of air filters,” Sherman says. “Just be sure to change the filters out before they get clogged up.”

Activated-carbon filters are great at removing odors, and ultraviolet (UV) systems use UV light to kill germs, bacteria, and viruses. Sherman also suggests researching “reputable brands,” including Dyson, Honeywell, and Blueair Air, when shopping for a reliable and efficient air purifier for those who share their home with pets. Many of today’s units have multiple layers to their filtration and can remove 99 percent of noxious material from the air.

The best air purifiers for pets run quietly as they work, with the loudest option measuring around 40 decibels. Select machines also have a sleep mode that operates silently through the night. Additional special features may include child locks, color-coded air-quality monitors, auto adjustments based on environmental changes, and washable and reusable filters.

Best of all, you may not even know it’s running. The Alen BreatheSmart produces just 49 decibels of sound when operating at its highest setting—comparable to moderate rainfall. It produces just 29 decibels on low, or about the same level of noise you’d expect to hear in a quiet library.

The BreatheSmart is a top option for homes with open-concept plans, such as great rooms that feature combo kitchen/dining/living areas. It can freshen the air at a rate of up to 350 cubic feet per minute (CFM) on Turbo mode. It fully refreshes the air in a 1,300-square-foot space every 30 minutes, so dander, fur, and other airborne pollutants don’t stand a chance.

The BreatheSmart also features set-it-and-forget-it capabilities as it comes with an air sensor that keeps the machine running at low speed when the air is fresh but automatically revs up when the sensor detects the presence of pollutants, so your home stays fresh without the need to adjust the air purifier manually.

What to Consider When Choosing an Air Purifier for Pets

Removing pet contaminants from indoor air generally makes a room smell fresher and can reduce the allergic symptoms associated with pets. Still, there’s more to getting the right one than just a quick search.

To get a good air purifier for a specific home and family, shoppers will want to consider room size, acceptable noise level, and portability. They might also determine whether innovative technology would be helpful.

Types of Air Purifiers for Pets

All air purifiers are made to refresh the air in a room, but they’re not all well suited for those who require a purifier for a pet-friendly home. Air purifiers use various methods for freshening indoor air. Understanding the benefits and considerations of each type helps in choosing the best one to clean the air in a home with pets.

HEPA Air Purifiers

If an air purifier has an industry-standard HEPA filter, it can remove up to 99.97 percent of airborne particulates at a size of 0.3 microns or larger, which includes pet dander and small smoke particles. To put that into perspective, a micron is only 0.00004 inch in length, so HEPA air purifiers will trap even microscopic particles that are too small to see with the human eye.

HEPA filters are dense and tend to clog quickly, though. Replacement HEPA filters are on the pricey side compared to other types of replacement filters. For this reason, the best purifiers for pets have one or more prefilters to trap larger particulates. This allows the costly HEPA filter to last longer—up to 2 years or more—before replacement is necessary.

Activated-Carbon Air Purifiers

Air purifiers with carbon filters keep odors down to a minimum. Activated charcoal, the filter’s main ingredient, can filter out whiffs of wet dog or cat litter box odors to help keep the home smelling fresh. Activated-carbon air purifiers also can come with additional air filters within the same unit, working double duty to remove odors and trap airborne particulates.

A carbon filter often serves as a prefilter before a primary HEPA or another type. Depending on quality, a carbon filter also will remove smoke and volatile organic compounds (VOCs) from the air and can get rid of cooking odors and many types of chemical smells.

UV Air Purifiers

Air purifiers with UV technology are designed to kill microorganisms such as viruses and bacteria. They perform the task by drawing in the air past a strong UV light stream that destroys the microbes.

By itself, a UV purifier will not trap pet dander or fur; however, some UV air purifiers also feature a HEPA or other type of filter. If this is the case, they can trap and remove pet fur and dander in addition to destroying airborne bacteria and viruses.

Negative-Ion Air Purifiers

A negative ion is an electrically charged oxygen molecule with an added electron. Negative ions occur naturally after events such as lightning strikes or as a result of bright UV sun rays. A negative-ion air purifier artificially produces negative ions, and rather than drawing in air and trapping contaminates, this type of air cleaner injects invisible puffs of negative ions into a room.

The negative ions are drawn magnetically to airborne particles, and they bond with the particles. As a result, they are too heavy to remain airborne, so they subsequently fall to the floor or furniture. While this process removes debris from the air, it doesn’t remove it from the room altogether, so sitting on the sofa or a chair can bring the home’s residents into contact with the contaminants.

Ozone Generators

Some people like the smell of ozone and associate it with thunderstorms since lightning creates ozone in the atmosphere. Ozone generators emit ozone into a room. Often, they’re used in conjunction with negative-ion purifiers, but the verdict is still out on whether they’re beneficial.

According to the Environmental Protection Agency (EPA), inhaling ozone might be detrimental to the human respiratory system and can result in symptoms such as coughing, difficulty breathing, and throat irritation. As is the case with negative-ion purifiers, ozone generators don’t actually remove pollutants from the room; they just give the room a fresh rain scent.

Room Size

Air purifier labels might indicate the approximate square footage of the room that the units will treat effectively. Alternatively, they may be labeled as either small, medium, large, or whole-house purifiers.

  • Small: A small air purifier will treat the air in rooms up to 300 square feet, making it suitable for bedrooms, nurseries, and other smaller spaces.
  • Medium: Designed to clean the air in rooms up to 700 square feet, medium-size purifiers are often chosen for use in family rooms, combo kitchen/dining rooms, and rec rooms.
  • Large: Suitable for use in spacious rooms of up to 1,900 square feet, large purifiers are well suited to homes with open floor plans.
  • Whole-house: A whole-house purifier installs on the home’s HVAC trunk and purifies the air as it circulates through the system. This type of air cleaner should be installed by an HVAC professional. Not all HVAC systems accommodate a whole-house purifier. The system must be powerful enough to draw air through the filter without straining the HVAC system.

EPA Rating

The EPA recommends the use of air purifiers to help clean indoor air, and some purifiers qualify for an EPA Energy Star certification. That means the unit adheres to strict energy-efficiency guidelines, but it does not ensure the unit will clean the air effectively.

Selecting an Energy Star–certified purifier is an option for those wanting to conserve energy and reduce their carbon footprint. The EPA, however, does not certify any particular brands of air purifiers or air cleaners as being better than others. It does, however, suggest that purifiers with a higher clean-air delivery rate (CADR) rating might be more efficient at removing particulates from the air.

CADR Rating

Some air purifier manufacturers voluntarily participate in a program developed by the Association of Home Appliance Manufacturers that rates purifiers based on laboratory testing of how much they reduce airborne pollutants within 25 minutes.

The results lead to a purifier’s CADR by multiplying the particle reduction with the amount of air that moves through the purifier in cubic feet per minute. For example, if the purifier operates at 300 CFM and reduces 80 percent of particulates during testing, its CADR will be 240.

In general, the higher the CADR number, the more pollutants the purifier will remove from the air. The CADR scale runs as high as 450. However, some of the best filters, including the HEPA kind, might have a reduced CFM airspeed due to their density, so they actually remove more airborne pollutants yet come with a lower CADR.

Air-Quality Indicator

Air purifiers for pets with integrated air-quality indicators clean the air in the room and monitor and display air quality with digital readouts, putting this type at the top of the list for allergy sufferers who want to know the status of the air in the home. The indicator might provide a simple bar graph indicating “good, fair, or poor” air quality or be more advanced to indicate the specific particulate matter present in the air, such as the amount of dust, pollen, pet dander, and more.

An air-quality indicator helps allergy sufferers know how safe the room’s air is to breathe. Some air-quality monitors adhere to the EPA’s Air Quality Index, which uses a color-coded system to alert residents to the indoor air quality of a specific room.

For example, green signals good air quality, yellow is moderate, and red indicates unhealthy air quality. Residents can turn the purifier speed up or down as necessary. Some models automatically adjust operating speed based on air-quality monitor results.

Noise Level

Some, but not all, air purifiers list a noise rating in decibels. Manufacturers are not required to include a noise rating, but those who feel their purifiers are especially quiet might do so as a selling point. For reference, a purifier with a 50 decibel rating is approximately as loud as the sound of a modern refrigerator running. A decibel rating of 30 is closer to a whisper from across a room.

Noise levels typically depend on the fan’s quality, which is the element that produces sound. For the most part, cheaper units make more noise because they don’t contain the sound-insulating features that damper fan noise. Most purifiers range from around 30 to 60 decibels, with 30 to 40 being the average.

Smart Technology

Many of today’s new small appliances come with the option of syncing to a smart-home system to allow the user to operate the unit remotely from a smartphone or tablet.

A smart air purifier works in the same manner as its nonsmart cousins, but it offers the option of downloading an app where the user can monitor the filter’s status, receive alerts when air quality exceeds a predetermined range, or turn on the unit via voice commands. These usually require a home Wi-Fi network.

Bluetooth, another common smart technology, also allows the user to operate the purifier via a smartphone, with no Wi-Fi network necessary. However, the user must be within range (usually 75 to 150 feet) for the smartphone to connect with the purifier through Bluetooth.

Portability

Small, lightweight purifiers (under 20 pounds) are relatively simple to carry from room to room as long as they feature a sturdy handle for carrying. Heavier units are more difficult to move unless they come fitted with caster wheels to allow users to roll them from one spot to another.

Most of today’s purifiers weigh less than 30 pounds, but if moving the unit will be an issue, look for a lightweight model with wheels. Alternatively, plan on purchasing additional purifiers to keep in various rooms.

FAQs

Reducing pet dander, dust, and other contaminants leaves a home smelling and feeling fresh. The best air purifiers can significantly reduce the airborne pollutants commonly found in pet-friendly homes. Here are answers to some of the most frequently asked questions we get about air purifiers for pets.

Q. Do air purifiers help with pet hair?

Yes, depending on the type. A purifier that draws air through one or more filters will trap any pet fur that’s floating around. Note that negative-ion, ozone, and UV purifiers will not unless they feature additional filters.

Q. Do air purifiers get rid of pet odors?

Yes, some air filters will get rid of pet odors, but they need to contain the right type of filter, as HEPA filters and prefilters do nothing for odors. Activated-carbon air purifiers will neutralize pet smells and other disagreeable odors, including smoke, VOCs, and cooking smells.

Q. What are the different types of air purifiers?

The five most common air purifiers are HEPA, activated carbon, UV, negative ion, and ozone. Each type of air purifier works differently, using a specific filter, UV light, or ions to remove particles from the air, but the most effective purifiers for pets have a prefilter, charcoal filter, and HEPA filter model.

Q. What type of air purifier do I need if I have problems with asthma?

People living with asthma will want to opt for a high-end HEPA purifier, such as the Rabbit Air air purifier for pets, which features six stages of filtration to remove a maximum amount of pollutants. Before buying, asthma sufferers may want to consult a doctor to see whether a different purifier might be better suited to their needs.

Q. How long do air purifiers last?

An air purifier can last 3 to 5 years or longer if it’s well maintained. To get the most life out of the unit, the prefilter, charcoal, and HEPA filters should be changed as they become clogged or within the time frame recommended by the manufacturer.
