Countertop reverse osmosis
What the category actually costs.
Prices captured from the sellers' own listings on 31 July 2026. We have not yet tested these units ourselves. Two of these moved up about 5 per cent in the two days since our previous capture, while being shown as a discount, which is why this line carries a date.

On money, before you click anything
We do not currently earn a commission on any link on this page. We have applied to affiliate programmes in this category and expect to be accepted. The moment that happens, this notice will say so, in this position, above the table, before you click. It will never move to the footer.
We are a publisher, not a shop. We do not sell, ship, warranty, or take payment for anything.

Prices and review counts as the sellers displayed them on 31 July 2026. Certification is quoted as the seller lists it, not as we have verified it. Checked by tools/check_prices.py, which fails when a figure has moved.
How we chose what is in this table
Countertop reverse osmosis only, because carbon does not change the result of a boil test and a boil test on a carbon filter would be dishonest. Prices are what the seller displayed on the capture date, not a negotiated or affiliate price. Certification is quoted exactly as the seller lists it, not as we have verified it. Anything we have not captured says so rather than showing an empty cell.
