Buying an Air Purifier
Today's energy-efficient technology makes homes air tight, holding warm air inside during the winter and cool air inside during the summer. Unfortunately, the home isn't allowed to breathe and opening a window isn't always an option.
Air purifiers are designed to reduce allergens in the home and are good for allergy and asthma sufferers. Lowe's is happy to provide this air purifier consumer guide as a to you.
Where do all the air pollutants and allergens in my home come from?
Air pollution, in general, is a top environmental concern in the world today. Indoor air pollution is part of that concern. According to the Environmental Protection Agency, indoor air pollution levels can be up to five times higher than pollution levels outside. Most Americans only spend about 10% of their time outside.

What type of air purifier do I need?
The most important thing to look for when you buy an air purifier is the correct size for your room. Air purifiers are portable and can be moved from one room to another, provided the rooms are similar in size.
What size do I need?
The first thing you need to know when purchasing an air purifier is what CADR means. The Clean Air Delivery Rate (CADR) seal program was developed by the Association of Home Appliance Manufacturers (AHAM) to help consumers choose air purifiers. CADR is based on the cubic feet of air a purifier can filter per minute. The higher the CADR number the faster the unit cleans the room's air. Purifiers with the CADR seal remove tobacco smoke particles, animal dander, mold, mildew, dust and pollen particles. Use the following formula to decide which CADR is correct for your room:
If an air purifier isn't available with the exact CADR you calculate, round up. For instance, if your room size requires a CADR of 204, purchase one with a CADR of 220.
If you have a room with ceilings higher than 8', move up to the next level CADR for a larger room. If you have an open floor plan, purchase two small units. The units can be moved to different areas in the room, cleaning the air more efficiently than one unit.
What else should I look for?
Different brands of air purifiers have different features. Here are some additional features to look for:
