QUESTIONS ANSWERED.

Which IAQ product actually matters on the Gulf Coast?

Whole-home dehumidifier, first. Coast humidity is the source of most IAQ problems: mold, mustiness, dust mites, off-gassing. Solve humidity, most of the other symptoms fade. UV and HEPA are optional add-ons after dehumidification is handled.

What humidity level should I aim for?

45% to 55% relative humidity indoors. Above 60% invites mold and dust mites. Below 30% dries out sinuses and wood. Coast homes often sit at 65-75% without whole-home dehumidification, which is why the mildew smell shows up.

Does UV really kill viruses and bacteria?

Properly sized UV-C in the airstream reduces microbial load, yes. It's not magic and it doesn't replace filtration. We install both UV and media filters together for full-spectrum reduction.
