Residential Water Treatment Softening

Air Sulfur & Air Iron Filters

Impression® and Impression® Plus Air Sulfur (IMPS) and Air Iron (IMPFE) Filters are extremely effective in removing sulfur and iron, commonly associated with problematic well-water. The systems use air-injection to oxidize sulfur or iron into precipitates that can be readily filtered and removed.

Air filtration is environmentally safe — no toxic chemicals are used. The result is simply refreshingly good water from the tap, every time. Watch how it works!
