Downtown Charleston, SC

Cleaner indoor air for Downtown Charleston’s historic homes and modern residences.

Downtown Charleston’s historic homes bring charm and challenges: aging HVAC, salt air, dense oak pollen, and humidity that trap odors and allergens inside. OasisPure brings AtmosAir bi-polar ionization to homes from South of Broad to Harleston Village, treating air and surfaces so your historic or modern residence stays fresh and healthy.

Clean Air Downtown Charleston
How It Works

The AtmosAir unit installs into your home’s existing HVAC system, treating every room as air circulates. Bi-polar ionization deactivates airborne pathogens, binds allergens, and breaks down odors in real time. It runs silently with no moving parts, so it works continuously throughout your home without noise, chemicals, or disruption to your daily routine.

What Our Clients Say About Us

We installed an AtmosAir ionization system from OasisPure and immediately noticed a difference. We’ve experienced a clear improvement in indoor air quality. The air smells fresher and food odors don’t hang around. The whole house just feels cleaner and more comfortable. It’s one of those upgrades you don’t see, but you absolutely feel.

Filtering the air is important. Everything pieces together. If it all fits together properly, nicely, then your blessed. And we are blessed!
Howard
I’ve personally tested the system in my own home and our office, and the difference is real. It works by releasing ionized air molecules that help eliminate odors and neutralize mold spores and pathogens. The result is that crisp, clean smell you get after a fresh rain.
Property Manager
We do a lot of cooking during the week. Salmon, fajitas, steaks. I do the cooking and it not pretty – lots of flavor and a bit of smoke. Now that we have the OasisPure whole home ionization system, those odors don’t linger. We love it!
Ryan
This building smells so good and clean because of the air purification system that many places don’t have that enables for a nice environment when you walk in.
