Air Purification Systems in Cary, NC

For allergy relief, we typically recommend a high-MERV media air cleaner installed in your ductwork. It captures pollen, dust mites, pet dander, and mold spores far better than a basic filter. True HEPA filtration usually needs a dedicated bypass unit, because a HEPA filter is too restrictive for most home systems. For severe allergies, we may add UV germicidal treatment to keep the coil clean.

Significantly. A duct-mounted whole-home system treats all the air circulating through your HVAC, covering every room automatically. Portable units only treat the single room they're in, require multiple units for whole-home coverage, and can be noisy. Whole-home systems are also lower maintenance with longer-lasting filters.

The impact is minimal. Most whole-home purification systems add negligible electrical draw. Higher-efficiency media filters do create slightly more static pressure than a basic 1-inch filter, but properly sized systems account for this. Any minor energy increase is typically offset by reduced HVAC strain from cleaner coils and components.

It depends on the system type. High-efficiency media filters typically last 6-12 months, UV lamps last 12-24 months, and photocatalytic cells can last 2-3 years. We set up maintenance reminders and can include filter replacements in an annual maintenance plan for convenience.
