Just like you I love animals – but pet dander can be a problem. Especially for those of us who have indoor pets. It seems like I’m always sneezing or feeling the symptoms of pet allergies because of the dander in the air.
There are so many air purifiers out there to choose from. You may be asking that very question – which air purifier is best for pet dander?
I’ll cover some basic information you need to know about pet allergies and show you some of the best air purifiers for your money to relieve pet dander problems, along with some brief reviews to help you decide.
Infographic – Pet allergies and pet dander facts
In order to best understand what type of air purifier we should decide on it is best to understand what kind of problem we really need to solve. There are many misunderstandings and a lot of bad information out there about allergies – especially those caused by being around pets, as well as many items in the air around us you may have never heard of.
What is pet dander?
Pet dander is actually made up of skin flakes shed by pets. These in turn cause an allergic reaction in humans. It’s carried by the fur of pets and is also distributed by the air around you.
Pet dander, just like human skin cells we all shed, is what causes dust mites to thrive. This is another major source of allergies you’ll have to worry about! So in fact reducing pet dander helps you in more ways than you may have realized.
Another fact: Although cats are found in fewer homes than dogs they account for more allergies when compared to dogs. Also, male cats produce less allergen material than female cats. Interestingly, enough, older animals have been shown to actually produce more dander skin shedding than younger pets.
Facts & myths about pet allergies
Myth: A common belief is that when you begin feeling the symptoms of pet allergies (red or puffy/itchy eyes, sneezing, itchy feeling, and more) it’s because of pet hair around you & circulating in the air.
Truth: Pet allergies are not caused by pet hair but their skin secretions (from pet dander) as well as their saliva to a lesser extent. However, pet hair can be undesirable and somewhat irritating to a degree, too.
Dander is actually an informal name used to describe material that is shed from the body of animals, including humans, which have feathers, hair, or fur. Think of it as dandruff but on a lesser level.
Myth: Some breeds of pets product cause less allergies than others
Truth: Breeds with shorter fur may carry few allergens than other breeds, but the fur is not the primary cause of allergies. Short haired breeds still contribute to allergies just as much as other breeds. There is no such thing as a non-allergenic dog or cat!
Note: While it’s true that no animals are completely hypoallergenic (meaning they don’t cause allergies) the amount of hair they produce can vary. For example there are a number of dog breeds that don’t shed much or at all and can reduce the amount of pet hair in your home.
Why pet dander is hard to deal with
A microscopic image of pet dander and organic proteins produced by a pet which triggers allergies in humans.
Pet dander is microscopic and can be moved around your home via house dust and even provides food for dust mites which feed off of skin particles leaving the bodies of human and animals. Even worse, when airborne dander can enter the open passages in your body like your nose, throat, and lungs causing allergies and in some cases more severe reactions due to the proteins found in the skin animals shed.
It also builds up on various surfaces and therefore over time becomes an problem that never goes away and only increases. Don’t underestimate how much difficult it is to deal with!
Opening a window lets in fresh air from the outside and can remove some odors and bring in clean air. The main problem with having allergens in an enclosed space is that they remain trapped there until removed.
Using an electric fan will not help and can actually trigger your allergies and disturb existing dust and pet dander causing more problems. Air fresheners do not actually remove odors and have no effect on contaminants in the air.
As allergens like pet dander and dust mite waste are incredibly small they’ll simply increase and increase until you can’t stand it any more. The dust mite population with flourish as well because there’s so much pet dander for them to feed on.
A quality air purifier is what you need
As mentioned earlier, pet dander and other allergens are microscopic in size and permeate the air around you. The only true way to alleviate your allergies and keep you home clean and fresh is by removing the problem at it’s source.
HEPA filters are the answer
High efficiency particulate air (HEPA) filters are designed to provide a standardized level of filtering quality. The standard was introduced in the 1950s in the United States. Filters claiming to be “true” HEPA in quality are proven to satisfy to very strict requirements:
- Can remove 99.97% of particles from the air passing through them
- Are able to remove elements & substances down to 0.3 microns in size
(Note that 1 micron is 1/1,000,000 of a meter – incredibly small!)
HEPA filters are made of very dense material and they’re extremely efficient in removing nasty air particles. They’re so efficient that out of every 10,000 particles in the air that pass through them, only about 3 will be able to escape! The remaining particulates are permanently removed from your air forever.
Because of this and when implemented in well-designed, quality product they are capable of making a huge impact on your pet dander & allergy problems. The filtering process is accomplished by pulling air through the filter where these particles are trapped permanently – leaving only fresh, pure air in the surrounding air.
A true HEPA filter addresses the source of the problem – pet dander & dust carried in the air that can come in contact with your skin and enter your breathing passageways. Additionally, good purifiers typically come with 1st & 2nd stage filters consisting of a more coarse filter for trapping larger elements like pet hair & large dust as well as a carbon/charcoal filter stage for trapping chemical substances in the air like odors.
Why not an ionizer or ozone generator purifier?
An ozone generator (shown here) can potentially produce high levels of ozone that may aggravate your breathing passages. Additionally, they don’t permanently remove particles like pet dander from the air around you. I don’t recommend them for pet dander problems. Stick with a proven and reliable filter-based product instead. You’ll be glad you did!
Other purifiers marketed work by generating ozone molecules from the surrounding oxygen molecules using a principle based on high voltage. The free molecules have an atomic charge which causes them to bond with particulates in the air.
Air purifiers sold as “ionizers” create electrical charges on air molecules to attract and trap airborne particles and kill airborne germs.
The problem is that while they do produce some clean air and can remove some pet dander, dust, and so forth, they aren’t even close to the performance of a HEPA filter-based purifier. Also even small amounts of the ozone produce may not be suitable for those with respiratory problems as they can aggravate their symptoms.
Many low-quality foreign made ozone generators are marketed as “air purifiers” and “air cleaners” but in fact both unsafe levels of ozone and have little to no impact on your air quality. Some people may even experience headaches too as a consequence of being around ozone.
