Do air purifiers work for pet allergies and odors?

Short answer:

Detailed Answer:

As long as there is pet, there are impurities in the air, and there is also an air purifier in the market for you. But not all purifiers perform the task of removing dander or odor or even pet hair. Henceforth, let’s consider the types of Air purifiers for pets.

Types of air purifier for pets allergies and asthma

Air cleaners in the market are based on four different types of air filtration technology, each of which has their capacity of cleaning the air. The types of air purifiers are:

  • HEPA Purifiers:

This is the most popular type of air purifier which has been proven to have the capacity to remove 99.97% of particles that floats in the air. They work solely based on the HEPA art technology i.e., High-Efficiency Particulate Arrestance.

Apart from removing smokes, pet dander, and other impurities that we are aware of, it is also very efficient in cleaning the air of microbes like viruses and bacteria.

This type of air purifier is so useful that they even trap mold; hence it has been the best and most suitable and capable purifier for pet owners.

  • Activated carbon purifier:

In most cases, the carbon filters are often an addition to the HEPA filter in most purifiers. They work based on the activated carbon technology which is capable of removing impurities by the help of installed carbon filter which is carbon pores that filter smoke, pet hair, pet dander, and even pet odors. These set of purifiers have not been found to be effective in microbe removal.

  • Ultraviolet Technology Purifiers:

These are the best cleaner for removing microbe in the air we breathe. Their working principle is based on the use of Ultraviolet light to trap and remove virus, germs, and bacteria. Although, they are still the best value for the money in the market they are generally not effective in removing pet impurities. They may only be used alongside the HEPA purifiers for absolute cleansing

  • Negative ions purifiers:

These are filter-less purifiers that capitalized majorly on the power of ions. Anions and cations are used instead of the filter. These charged ions are arranged on the plate where they remove impurities by attracting them unto the plate. As good and economical as they could be, they are inferior at removing microbes in the air. The safety of negative ions depends solely on the ozone level generation

Best air purifier for removing pet hair, dog smell, pet allergies, and pet dander

When particles like cat dander or even dog odor are removed from your indoor air, it means you breathe in less of them which in turn reduces your allergic reactions to the cat or your pet’s dander. The same goes for other pets

The major function of Air purifiers is to filter the air around us so that it is free of impurities; it goes as far as removing dust and other contaminations from the atmosphere such as bacteria, mold, dust, smoke, etc.

Air purifiers also carry out filtration of pet dander released by pets and other animals in the home. Therefore, as long the purifier is made of HEPA filter, it can certainly help in reducing pet allergy up to less than 0.5% if not completely.

Therefore, you might also want to ask that will an air purifier help with cat or dog allergens if it doesn’t contain HEPA filter? I would say NO, WHY? You only get to notice a positive change in your pet allergy reaction levels only when your air cleaner contains a HEPA filter.

In short, since you wouldn’t want to get trade your anima pet for anything, it’s advisable you purchase a HEPA air purifier for your health sake.

 Considerations for choosing the best air purifiers for pet allergies and pet odors

  • HEPA filter:

The most important component to consider when purchasing an air purifier is the presence HEPA filter, because this is what traps the micron particles in the air. The absence of this in the filter would reduce the efficiency by a large margin and would leave the indoor air quality of the room with much undone.

  • Other filtering abilities:

some air purifiers are designed to filter not just dust particles and pet dander but have other filtering capacities such as VOC (volatile organic compounds) filtering capacity. VOC are among the smallest particle in the air and may not be caught by just any filter; they are compounds that turns to vapor at room temperature, e.g., alcohol, formaldehyde, etc.

Henceforth, some air purifiers are treated carbon with a porous surface that absorbs these chemicals and other odors.

  • CADR number: 

The clean air delivery rate is a rating system created by the Association of Home Appliances Manufacturers to evaluate the quality of air purifiers when dealing some particular pollutants. The higher the CADR number, the faster the purifier cleans the air of that particular pollutant.

  •  Noise:

This may seem irrelevant but sounds from device operation might be very intolerance sometimes that you might likely be thinking of even considering switching it off. Better still, you should consider going for the unit that whisper quietly.

  • Cost:

This is very important. You shouldn’t consider only the cost of buying but also the cost of operating and maintaining the purifier. There may be continuous expenses like electric bill and filter replacement to keep your unit working. All in all, ensure that you calculate the monthly cost before opting for any of the purifiers.
