The air inside our homes can be significantly more polluted than outside. The reason we have pollutants in our air include smoke (including from cooking and candles), pollen, bacteria, and mold, as well as particles generated from the use of cleaning and grooming products. If you’re a pet owner then you can add pet dander to that list. We've rounded-up the best air purifiers for removing harmful particles from the air inside your home.

Winix HR900 Air Purifier

Extra protection against pet dander and odors

The Winix HR900 is the best air purifier for pet owners. Larger particles, such as pet hair and dander, tend to be a particular problem when you share your home with pets. The Winix HR900 has two pre-filters including an Ultimate Pet Pre-filter for an extra layer of protection against pet-related dust and dirt. Its color-coded system of lights offers real-time feedback on your air quality at a glance and in auto mode it will automatically adjust the fan speed, ramping up when poor air quality is detected and dropping down to save energy when air quality is good.

Clean larger spaces

The Blueair Blue Pure 211+ is a well-designed air purifier, made for large rooms, with great purification performance. It’s 3 stage filter system doesn’t include a True HEPA filter, which is quickly becoming the standard for air purifiers, but it does include its own particle filter that uses HEPASilent technology to combine mechanical and electrostatic filtration, still capturing minute particles. Combined with 360-degree air intake and its powerful motor, the Blueair Blue Pure 211+ is an air purifier that performs brilliantly and has the CADR ratings to back it up.

Whirlpool Whispure Air Purifier

Improves air quality of large rooms

The Whispure’s Clean Air Delivery Rate (CADR) is so high it removes smoke, dust, pollen, and more from indoor air with ease. It handles cleaning the air in rooms up to 487 square feet in size. It runs quietly, too. The Whispure only produces 55 decibels (dB) of noise on its highest setting, which is quieter than normal conversations and about as loud as moderate rainfall. It has four speed settings plus both a Turbo and Sleep mode. 

Choosing the best air purifier for you 

When buying an air purifier the most important question you need to ask yourself is what exactly do you want the system to do? Specific air purifiers, often because of how they have been designed, are expert at certain types of purification, while others have a focus on cleaning specific room sizes.

For example, if you have pets in your home and have one or more family members who suffer from allergies, then you should probably be looking for an air purifier that scores well in the removal of pet dander (flecks of skin shed by cats, dogs, rodents, birds and other animals with fur or feathers).

Equally, if you’re looking to outfit an open-plan kitchen-diner apartment then you should be looking for a different air purifier than if you are trying to clean the air in a house bedroom - after all, you’re going to want to consider smoke in the former far more than in the latter.

Obviously, price and portability are also factors to consider. You can expect to spend a couple of hundred dollars on an air purifier, however that doesn’t mean you should discredit models that are cheaper or more expensive, either. Evaluate what you need and what you can spend, do your research, browse the best air purifiers going, and then pull the trigger - by following this course we’re confident you’ll find the perfect air purifier for you.
