Common questions
Everything you need to know before you buy.
What contaminants does it remove?
The NU Aqua 5-Stage system reduces up to 99.9% of contaminants including lead, PFAS, chlorine, fluoride, arsenic, nitrates and pesticides. The included PPM meter lets you verify the difference immediately after installation.
Can I install this myself?
Yes — most homeowners complete the install in under an hour with no plumbing experience. The system includes color-coded tubing, quick-connect fittings, and a step-by-step video guide. Our lifetime support team is available Monday–Friday if you need help.
How is this different from a Brita or pitcher filter?
Pitcher filters remove 10–20% of contaminants and can't touch heavy metals like lead or PFAS forever chemicals. Reverse osmosis removes 99.9% — including everything a pitcher filter misses. It's a fundamentally different technology.
What if my water pressure is low?
If your home's water pressure is below 45 PSI, we recommend the version with a booster pump. Not sure of your pressure? Our support team can help you check before you order.
How often do filters need replacing?
Pre-filters (stages 1–3) every 6–9 months. The RO membrane and post-carbon filter every 12 months. Replacement filters are available on our site and are among the most affordable in the industry — keeping your annual cost far below bottled water.
What does the 120-day guarantee cover?
Everything. If you're not completely satisfied for any reason within 120 days, send it back for a full refund. No questions, no hassle, free return shipping. We also cover manufacturing defects for 3 full years.
Is it HSA or FSA eligible?
Yes — NU Aqua systems are HSA/FSA eligible through Truemed, which means you can use pre-tax dollars to purchase. This saves most customers an average of 30% compared to paying out of pocket.
Does it fit under my sink?
The NU Aqua 5-Stage system is designed to fit under any standard kitchen sink cabinet. The compact housing requires no drilling and the color-coded tubing routes cleanly regardless of your cabinet layout.
