VIQUA VH410 UV System (18 gpm) review
By Daryna Klochko · Published · Specs checked Oct 14, 2026 · 
Scores 9/10, tied for 3rd of the 5 UV systems we track. At $829 it costs the same as the category median of $829. VIQUA describes it as certified or tested, but no NSF or WQA listing matched the model name; none of the 5 UV systems has one on record. Its cartridge cost of about $158 a year is the highest of the 5 UV systems with a stated cartridge cost.
