Filter Types
The type of filter used by your air purifier is one of the most important considerations when selecting one for pet-friendly homes. The best choice would be a HEPA filter, which stands for High-Efficiency Particulate Air. A HEPA filter is capable of trapping particles as small as .3 microns, such as pet hair, dander, pollen, and dust mites—all common sources of allergies or asthma triggers in the home. Additionally, some models come with pre-filters that are designed to capture larger particles before they make their way through the system and clog up the main filter.

Room Size
Air purifiers are also rated based on their ability to cleanse rooms of certain sizes. Be sure to check the room size specifications before purchasing an air purifier as this will determine how well it works and how often it needs to be cleaned or replaced. A unit that's too weak won't do much good at all while one that's too powerful may end up costing more money than necessary over time due to increased electricity consumption and higher maintenance costs.

Noise Level
Air purifiers can be quite noisy so another important factor is noise level. Look for models with adjustable fan speeds; lower fan speeds can help reduce noise levels while still providing effective cleaning power. Additionally, some models come with sound insulation panels that help absorb sound waves and reduce overall noise pollution in the room where it’s located.

An air purifier is an essential appliance for any home with pets—but not all models are created equal! When shopping for an air purifier for use in homes with pets, make sure you consider filter types, room size, and noise level before making your purchase decision. Doing so will ensure you get the best value and longevity out of your new appliance while also providing superior indoor air quality in your home!
