When it comes to improving your home’s indoor air quality, it’s important to understand how air purifiers operate and how they help people improve their quality of life. Air purifiers work non-stop to ensure we breathe in fresh, clean air 24/7. They come in different forms, such as negative ion emitters, heaters or UV lamps, and they all share the common goal of reducing odors and pollutants in the air. Here your leading HVAC air conditioner repair expert lists three things you need to know before buying an air purifier.
Choose the Right Filter For Your Room
Before deciding on which air purifier to get, make sure you’ve considered the space you’ll be putting it in. Placing a large humidifier in a small room will be too much, as it will consume more energy than necessary. To help you decide on the right size, refer to the “air changes per hour” information on the purifier’s specs sheet. To put it in perspective, a small air purifier can turn over the air in a 350-square-foot room eight times but only achieve four changes in a 700-square-feet room.
Take Note of the Purifier’s CADR Rating
A CADR or “clean air delivery rate” rating measures how effective a purifier is at filtering harmful particles in a specific area. A CADR reading of 300 indicates that the purifier can reduce pollutants while adding 300 cubic feet of fresh air per minute. A good rule of thumb to remember is that the higher the CADR rating, the higher the number of pollutants removed and amount of clean air added. This also aids in improving your indoor air quality testing results.
Consider the Noise the Air Purifier Makes
Most air purifiers have internal fans that pull in air for the filters to clean. Some of these fans make little to no noise, while others make a humming sound when you turn up the settings. You should also consider where you’re putting the air purifier. Putting it in your workplace or your bedroom can be distracting due to the noise, so be sure to refer to the purifier’s spec sheet to determine its decibel rating. A rating of 17-40 dB is considered relatively low.
