Instapure Essentials Replacement Filter 4-Pack (R2C, R2) Tested & Certified to ANSI/NSF 42, fits F2 Essentials & F5 Complete Systems

This filter attaches to the sink faucet and is simple to install an replace when needed. I use one on the faucet in my camper and it works great. Nothing bulky about this one and when space is limited, it is a great buy.

Works well.

THEY REALLY MAKE THE WATER TASTE SO SO MICH BETTER

Works great

I've tried several other brands most claiming to filter the same, this brand work's best for my needs.

Very reliable and good price

Been using for a while and always try to keep supplied. Great tasting pure water for cooking aND just daily use at home. Fill the bottle and take to work or keep in the car. Cheaper than bottles. Live in old building in NYC so really need it. Does not last very long but good for the price.

Have had an instapure filter for years. Only one still around with a pass thru for connected devices, in my case portable dishwasher and washing machine. Water thru filter has always been crisp and refreshing.
