Reasons to Get an Air Purifier 

There are many reasons you might need an air purifier - your city might be heavily polluted, your health might require exceptionally clean air, or your living situation dictates the need. Breathing in particles for an extended period of time can cause health issues in anyone or exacerbate those already present, such as asthma. Inhaling particles found in dust and smoke can irritate lungs, leading to asthma attacks.

Air purifiers can also help those suffering from seasonal allergies and those with pets in the house. Pollen is brought in from the outdoors and will continue to circulate in your home if the air is not cleaned. Air purifiers capture pollutants and give you much-needed relief from allergy symptoms and from the effects of pet dander.

What Size to Get 

No matter how large your house is, you probably have only a few spots you like to hang out in for an extended period of time. Think about where you spend the most time and place air purifiers in those rooms. If you work from home, placing one in your home office could be the best place. If you have trouble sleeping, keeping an air purifier running while you sleep could be the best option.

No matter where you place the purifier though, you need to take into account the square footage of the room.

Small air purifier is best for spaces up to 299 square feet. Medium purifiers can cover 300 to 699 square feet and large air purifiers can be placed in a space that is 700 to 1,900 square feet. 

Which Features to Look For in an Air Purifier

Buying an air purifier is like purchasing any new tech product – they come with a lot of features. You should compare different purifiers and see which features are most important to you given your space and lifestyle.

Here are some common features to consider:

Energy Star-Rated:

Air purifiers that have an official Energy Star rating will save money and conserve energy

Air Quality Indicators:

You will need to look at the noise rating especially if you are going to have the purifier running while you are sleeping. A rating of less than 50dB is suitable for the bedroom.

Other Features:

Filter change indicators, Caster wheels, Multiple fan speeds, and remote controls.

The Best Spot for an Air Purifier 

Air purifiers give you clean air but are only able to filter a certain size space. First choose the spaces that you spend the most time in. Then, if you are feeling like you need more areas cleaned, place more units throughout the house.

There are also spots to avoid if you want to get the most out of your purifier. Do not place air purifiers in corners, near other devices, or behind/below furniture.

Determining Maintenance Level 

All air purifiers have filters in them, but different filters require different levels of maintenance. 

HEPA Filters:

These filters last one year, depending on use.

Carbon Filters:

Activated carbon filters last up to six months.

Pre-Filters:

Pre-filters generally last up to three months. 

Air purifiers in your home can give you relief from a number of health issues, have you sleeping more soundly, and give you peace of mind. Keep in mind the above and get ready to breathe easy!
