What's filtering your air?

Buy a filter. Don't be one.

The best filter in your home is your heating and cooling system. Every time it runs, it pulls dust, allergens and other contaminants out of the air. The second-best filter is your lungs.

The Environmental Protection Agency names indoor air pollution one of the top five environmental risks to public health. The right filter, or a whole-home air cleaner, means your system catches more of what's in the air before you breathe it.

A clean filter also lowers operating costs and helps your equipment last longer and break down less often.

Whole-home vs. portable

Why a system beats a plug-in.

Many people buy standalone air purifiers. They can work well in a small area or a single room, but they aren't built to handle a whole house.

An air cleaner installed on your heating and cooling system spreads clean air every time the system kicks on, reaching your entire home. There's nothing to move from room to room.

Air scrubber or UV light? People often confuse the two. A UV system destroys micro-organisms that pass directly through it, and that's all it's designed to do. An air scrubber also works on the air throughout your home, reducing allergens, odors and dust.

How often should I change my air filter?
Every one to three months, depending on the type. The filter you use changes the interval more than most homeowners realize. Types of HVAC air filters.
Is a whole-home air cleaner better than a portable purifier?
For the whole house, yes. Portable purifiers can be effective in a single room. A system installed on your HVAC cleans the air everywhere it circulates, every time it runs.
What's the difference between an air scrubber and a UV light?
A UV system destroys micro-organisms that pass directly through it. An air scrubber goes further, working on the air throughout your home to reduce allergens, odors and dust.
Does a clean filter really save money?
Yes. A clean filter lowers operating costs, and with a fresh filter your equipment lasts longer and breaks down less often. A clogged filter restricts airflow and can even cause a system to fail.
Do you also clean air ducts?
Yes. Clean ducts and good filtration work together. About air duct cleaning.
