What is the best replacement filter for pet allergies?

The most effective air purifier filter for pet allergies is one that tackles both airborne allergens and persistent pet odors. PuroAir Filter Replacements are designed with pet allergy relief in mind. Each purifier filter has 3-layers of defense against large particles, fine allergens, and persistent odors. The heart of each PuroAir air purifier is the best-in-class multilayer HEPA filter. It's composed of a pre-filter screen layer to filter large particles, a HEPA filter layer to reduce up to 99.9% of microscopic allergens4 and pollutants, and an activated carbon filter layer to mitigate odors, smoke, and harmful VOCs.

The HEPA filtration system effectively filters airborne particles like dust, pollen, pet dander, and other allergens3, ensuring the highest quality air and a healthier environment in your home or office at all times. In the center of the PuroAir filter is the activated carbon layer, which attacks stubborn pet odors, leaving your home smelling fresh and clean!

What is the best home air filter for pets?

The best AC filter for a home with pets is one with a high MERV rating and additional features to stop allergens in their tracks. The higher the MERV rating, the more effective the filter is at reducing smaller particles. PuroAir Mega HVAC Filters offer a rating of MERV 13 (for smaller particles like pet dander, dust, and pollen).

HVAC Filters are rated on the Minimum Efficiency Reporting Value (MERV) scale (1–20). The higher the MERV rating, the better filtration. However, some higher MERV-rated HVAC filters may reduce airflow if not matched to your central air system, AC unit or furnace. PuroAir Mega HVAC Filters have one of the highest MERV ratings of any residential home air filter at MERV 13, while still allowing strong airflow into the system.

PuroAir Mega HVAC Filters include three filter layers for one of the most effective and efficient home air filters on the market. The Mega Filter has a pre-filter to filter larger particles, MERV 13 filter layer blocks fine air particles down to 1 micron, and an activated carbon layer to create a barrier against odors, gases, smoke and other pollutants.

Mega MERV 13 HVAC Filter Benefits:

  • Flexible size options and more on the way! Perfect fit for small, medium, or large homes.
  • Optimized air velocity: 286 FPM (Feet Per Minute) ensures great filtration without straining your system.
  • Designed for increased airflow while maintaining low resistance.
  • CarbonTech™ activated carbon filter is derived from renewable coconut shells, not coal.
  • Microporous structure provides a large surface area for capturing pollutants.
  • Exceptional ability to reduce gases and odors.
  • Mega Filter lasts 3x longer than fiberglass filters6.
  • Pleated filter design to mitigate more airborne pollutants.
  • Sturdy frame for easy installation and removal.

FAQs

PuroAir air purifiers, like the best-selling PuroAir 240, are equipped with HEPA filters that filter up to 99.9% of particles as tiny as 0.1 microns3, effectively filtering out pet dander before it irritates your airways. PuroAir air purifiers also include an activated carbon filter layer to adsorb odors from litter boxes, cages, and happy pets, leaving your indoor air fresh and pleasant.

For best results, it is important to replace the HEPA filter according to the manufacturer guidelines. We recommend the best-selling PuroAir 240 air purifier to help reduce odors and irritants that may be in the air from your dog, cat, or other pet.

Cat owners can learn more about combating allergy symptoms here: Air Purifiers: The Unsung Hero for Cat Owners.
The best air purifier for cat litter box smells and dust is one with a HEPA filter and an activated carbon layer. This powerful combination will help reduce particles in the air, and reduce unpleasant odors coming from the litter box. We recommend placing a small PuroAir air purifier near the litter box to help get rid of musty smells from urine and more before they travel to other rooms in your home.
Yes, air purifiers are a great investment for managing allergies, especially if you choose the right type and use it consistently. The key is to purchase a purifier with a HEPA filter. PuroAir HEPA (High Efficiency Particulate Air) Filters clean up to 99.9% of airborne particles, down to 0.1 microns3. These purifiers effectively filter small particles, including dust, pollen, pet dander, fur, airborne saliva, smoke, and odors, ensuring the air in your home remains clean and fresh.
There are a few ways to enhance the indoor air quality in a home with a pet. We recommend starting with the easiest solution: adding a HEPA air purifier or two around your home. This small addition will make a world of difference reducing unwanted odors and airborne particles like dander and fur immediately from your home.

Another solution for improving indoor air quality is by upgrading your home’s HVAC, AC or furnace filter from standard fiberglass to one with a higher MERV rating, like the PuroAir Mega HVAC Filter. The Mega Filter is rated MERV 13, which is one of the highest residential filtration ratings on the market. The innovative design allows more air to flow through, while reducing large and small particles, as well as adsorbing odors with the activated carbon layer. Try for yourself and experience the difference today!

If you are looking for the ultimate solution, build a bundle tailored for your home with a HEPA air purifier and MERV 13 HVAC filter. This whole home air filtration system allows the purifier to clean the air from the ground level, while the HVAC filter will intake pollutants and odors before they hit the HVAC, AC or furnace and then push purified air out of the vents.
HEPA filters are highly effective, capturing up to 99.9% of particles as tiny as 0.1 microns3. Considering that pet dander particles typically measure between 2.5 and 10 microns, a good quality HEPA filter can remove virtually all of them.
Yes, an air purifier can help reduce dog smell, but how effective it is depends on a few key factors. PuroAir’s CarbonTech™ Activated Carbon Filter layer is essential for odor reduction. The HEPA filter layer filters airborne particles, but activated carbon is what fights against odors and gases.

Keep in mind, air purifiers won't help much if the source of the smell (e.g., unwashed dog beds, carpets, or the dog itself) isn’t addressed. Make sure to bathe your dog with a vet-approved shampoo, wash their bedding often, and use an air purifier continuously for best results.
Yes, it’s true! Just like their human companions, pets can suffer from allergy symptoms too, including: itchy skin, watery eyes, sneezing, and even respiratory discomfort. These reactions are often triggered by the same airborne irritants that affect people: dust, pollen, mold spores, and pet dander. While we tend to focus on improving air quality for ourselves, our furry friends benefit just as much from a cleaner, allergen-reduced environment.

That’s where PuroAir steps in. Equipped with a HEPA filter, PuroAir purifiers filter up to 99.9% of airborne particles as small as 0.1 microns3. This includes the microscopic allergens that can aggravate your pet’s immune system and lead to chronic discomfort. By continuously filtering out dust, pollen, and dander, PuroAir helps create a healthier living space, reducing the allergen load in the air and giving your pets relief from symptoms they can’t explain but definitely feel.

Whether you have a sneezy cat, a dog with seasonal skin flare-ups, or a sensitive small animal like a rabbit or ferret, investing in high-efficiency air purification isn’t just a luxury. It’s a compassionate step toward their well-being. Clean air isn’t just for humans. It’s for the whole family.
  • HEPA filter: This is the most important feature, as it is the industry standard for capturing tiny particles. The filter should capture at least 99.9% of particles that are 0.1 microns in size, which include many common pet allergens.
  • Activated carbon filter: A filter with an activated carbon layer helps adsorb musky odors and Volatile Organic Compounds (VOCs), which can also irritate allergy sufferers.
  • Correct room size: Check the manufacturer's recommended coverage area to ensure the purifier is powerful enough for your room.
  • Quiet operation: If you plan to use the purifier in a bedroom, look for a model with a low noise level, especially at its lower fan settings or with a sleep mode.
  • Filter replacement costs: Consider the cost and frequency of replacement filters, as this is an ongoing expense.
  • Avoid ozone-producing models: Steer clear of ionic air purifiers or ionizers that produce ozone, as this can irritate the lungs and aggravate allergy or asthma symptoms.
We recommend avoiding ionic air purifiers or ionizers that produce ozone, as this can irritate the lungs and aggravate allergy or asthma symptoms. Even at low levels, ozone can be harmful to the respiratory system. It can cause coughing, throat irritation, shortness of breath, and chest pain, particularly in individuals with pre-existing respiratory conditions. When choosing an air purifier, it is vital to select models that do not generate ozone to ensure a healthier indoor environment for allergy and asthma sufferers.
Some factors that prove that your air purifier is effectively working are:
  • Improved allergy symptoms, like sneezing or coughing fits
  • Better sleep quality and less nighttime coughing
  • Noticeable reduction in odors from pets, cooking, or smoke
  • Less dust on surfaces in the room
  • Check the filter: A dirty filter proves it’s capturing particles
HVAC filters provide whole-house air filtration, but only when the system is actively running. This means that air is only being circulated through the filter, and therefore cleaned, when the heating or cooling system is on. If the system is off or in standby mode, no air is being filtered. The effectiveness of HVAC filtration depends on several factors, including the quality and rating of the filter (such as its MERV rating), as well as the volume and consistency of airflow through the system. Higher-rated filters like the PuroAir Mega MERV 13 Filter can capture smaller particles, including pet dander, dust, and allergens. For optimal performance, the system may need to run more frequently, or a dedicated air circulation setting may be used to keep air moving through the filter even when heating or cooling isn’t needed.

Air purifiers are typically portable devices designed to target air quality in specific rooms or areas of a home, such as bedrooms, kitchens, living rooms, or spaces where pets spend a lot of time. Their portability makes them a convenient solution for addressing localized air concerns, especially in areas where odors, allergens, or pollutants are most concentrated.

HEPA air purifiers are portable and ideal for targeting specific rooms such as bedrooms, kitchens, or pet areas. They can run 24/7 independently of your HVAC system and are highly effective at capturing up to 99.9% of airborne particles as small as 0.1 microns3, including common allergens, dust, pet dander, smoke, and odors. Many PuroAir models also feature smart air quality sensors that automatically adjust fan speed to maintain optimal air quality.

For optimal air quality, many experts recommend using both: a high-MERV HVAC filter, like the Mega MERV 13 HVAC Filter, for baseline filtration and HEPA air purifiers for precision air cleaning.
