Whole-Home Air Purifier Installation

While we all know that the air quality outside could be better, the reality is that the air quality inside your home can be even worse. That’s why Len The Plumber Heating & Air recommends installing air purifiers. These can use either UV lights or HEPA filters to neutralize contaminants in your home’s air.

UV systems are ideal for antibacterial and anti-viral protection and can be coupled with HEPA filtration to trap small particles like pollen, dust, and more. Whole-home air purifiers are installed directly in your ductwork to ensure that the air circulating through your home is as clean as possible.

There are plenty of things that can contribute to poor indoor air quality. These include household cleaners, mold, mildew, poor ventilation, etc.

Is there a test for poor air quality?

Are expensive air filters worth it?

Yes, and it’s true that you get what you pay for when it comes to filters. Higher-quality HEPA filters will trap contaminants as small as 0.3 microns.
