Air Purifiers: What You Need to Know

The air you breathe is an indispensable part of your daily life, which is why you need to make sure that you’re taking in fresh, clean air in order to stay healthy. Air purifiers play a vital role in improving your indoor air quality by eliminating pollutants and circulating clean air. Here the top home furnace repair company, Cooper Bros., lists some questions you must ask yourself before buying one.

Why Do I Need an Air Purifier?



Air purifiers are made to eliminate pollutants and allergens such as pollen and dust. They also help improve indoor air quality by removing mold spores, pet dander and smoke. However, some purifiers are designed for specific purposes, so it’s important to understand which particular irritants afflict you the most. Other air purifiers are especially effective for allergies, smoke, pets and asthma relief.

What Air Purifier Size Should I Get?

Before deciding on which air purifier to get, make sure you consider the size of the room you want to purify. Purchasing a larger purifier than necessary could result in a power-hog, straining your electrical system and possibly damaging your AC system, requiring AC repairsIf you have allergies or asthma, be sure to take note of an air purifier’s air change per hour, or ACH rate. This refers to the number of times a purifier can filter the entire space it’s put in per hour. Normally, an air purifier with the correct size turns over the air in a room four times per hour.

Use this size guide as your reference:

  • Small – For personal rooms up to 299 square feet

  • Medium-  Rooms between 300-699 square feet

  • Large – Rooms between 700 and 1,900 square feet

Where Should I Put My Air Purifier?

Normally, we would recommend that you place your air purifier in your bedroom, as you spend most of your time there. You should also keep in mind that air purifiers are meant to clean the air in one room only, so you might need to purchase more if you want to clean other rooms as well. You can also purchase models that are portable and include wheels and handles, making them easier to transport. If you do need to purify your entire home, there are whole-house air purifiers that can be tied into your HVAC system too.
