[Find your system →](/find-your-system) Type UV disinfection Flow rate 9-15 Warranty Lifetime tank, 5 yr electronics Maintenance Annual UV lamp replacement, sleeve cleaning Price tier $$ Best for Well water households with bacteria concerns ## Key specifications Class A UV at 40 mJ/cm², stainless chamber, 1" ports ## Our take The SpringWell UV Water Purification is a strong fit for well water households with bacteria concerns. As with any whole-house treatment decision, the right choice depends on your incoming water (hardness, chlorine vs. chloramine, any flagged contaminants) and the size of your home. If you haven't already, check your local water-quality data before committing. ## What problem does it solve? Inactivates 99.9% of bacteria, viruses, cysts and parasites such as E. coli, Giardia and Cryptosporidium using a 55-watt UV-C lamp. Disinfects without chemicals, taste or by-products, and protects every fixture downstream. ## Who is this for? Anyone on an untreated private well, on a shared spring source, or in an area under a recurring boil-water notice. Pair with a sediment pre-filter so the lamp can do its job on clear water. ## Pros - 99.9% inactivation of bacteria, viruses and parasites - Chemical-free disinfection; no taste, no by-products - Stainless chamber, lifetime tank warranty - Class A 40 mJ/cm2 dose meets NSF 55 Class A targets - Works with well, spring or boil-notice water ## Cons - Requires electricity 24/7 - Needs clear water; add sediment pre-filter - UV lamp must be replaced annually - Does not remove chemicals or hardness ## Can I install this myself? Moderate DIY (2-3 hours), needs an outlet Mount the stainless UV chamber vertically on the main line downstream of any sediment or carbon filtration so the lamp sees clear water. Connect 1 inch inlet and outlet with unions for easy lamp servicing, and plug into a 110V outlet on a GFCI circuit. Install a sediment pre-filter (5 micron or finer) ahead of the chamber if you do not already have one. ## What are the running costs I should foresee? About $90 to $120 per year for the replacement UV lamp (annual change) plus occasional quartz sleeve cleaning. Electricity is roughly $30 to $45 per year running 24/7. ## Frequently asked questions + Who is the SpringWell UV for?
