How Does This Compare?
THOMPSON FALLS (59873) has 293 recorded violations, including 15 health-based. All violations have been resolved, which is a positive sign for current water quality. Consider testing your tap water independently for added peace of mind.
Recommended Water Filters
Based on the contaminants detected in your area, these filter types may help improve your water quality.
Reverse Osmosis System
One of the few filtration methods effective at removing nitrates and nitrites. Essential for households with infants.
Targets:Nitrate, Nitrite, Dissolved Solids
Look for:NSF/ANSI 58 certified
UV Water Purifier
Uses ultraviolet light to neutralize bacteria, viruses, and parasites without chemicals. Ideal for homes with microbial contamination concerns.
Targets:E. coli, Coliform, Giardia, Cryptosporidium
Look for:NSF/ANSI 55 (Class A) certified
Always look for filters certified by NSF International for the specific contaminants you want to remove.
