If you share your indoor space with a pet, you may notice hair, dirt, dust, and even dander resting on the surfaces of the things around your home. While our canine and feline friends come with endless amounts of love, attention, and undivided attention, they also bring with them fur, which can trap grime and allergens that dirty up our personal spaces. Many pet owners like to have an air purifier in the home to help them combat pet-related allergies, and improve the overall quality of the air they, and their pets, breathe. Good air purifiers are known to relieve asthma symptoms, neutralize odors in the home, and even improve our quality of sleep thanks to their ability to remove harmful chemicals, bacteria, and dust from the air. Finding the best air purifier for your home will depend on the size of the space you need to treat, as well as the symptoms you wish to address with it.

What to Consider When Purchasing an Air Purifier

Size:​ Air purifiers come in a variety of sizes, and choosing the right size for your room needs will go a long way in achieving the results you want. While a small room can do with a smaller air purifier, rooms larger in size will need one that's built to handle that many particles floating through the air. An alternative to having one large air purifier in a room is to have two or more smaller air purifiers, depending on the size of your space.

Filter Type:​ Different types of filters do different things and offer varying degrees of efficacy, so finding the best one for you is important when shopping for an air purifier. Generally, air purifiers use three types of filters: HEPA, carbon, and UVC light. HEPA filters, or high-efficiency particulate absorbing filters, trap particles by making them stick to a fiber. Carbon filters filter gas and volatile organic compounds (VOCs) through a bed of activated carbon, and UVC light uses UV light rays to break down the DNA or RNA in bacteria and fungus, rendering them inactive.

Portability:​ For most people, the air purifier they purchase is intended for one room and will likely stay there the entire time. Some people, however, may wish to move their air purifier around with them or rotate it throughout different rooms in the home. Most air purifiers are not so large and heavy that they cannot be picked up and moved, but if you plan to keep yours on the go, you may want to search for one that's smaller in size or designed to move easily.
