iFilters 0.5 Micron 2.5 x 10 Carbon Block Under Sink Water Filter

About the best filter you can find for the money. I can taste the difference in the water. It has a very large filtering capacity. Removes lead, pesticides, giardia, and a whole bunch more. I change it every 6-8 months. Well worth the money.

I've been using countertop water filters for over 25 years. This is a good replacement filter. It filters to .5 microns but still allows a good flow compared to others I've used. I bought the countertop enclosure and filter from this company and have been very satisfied. The components are top notch, no shortcuts. I neglected to change the filter for about two years. Why? It worked really well for a long time and I didn't think about it. I think it works a year, not just six months, but after that, yeah, you should change it. The inside of the enclosure did need a disinfecting and cleaning, but other than that it's good as new. I then popped in the new cartridge. Ah...wonderful tasting water again. I use a countertop water filter because I'm persnickety about the taste of tap water. We actually have good "city" water where I live, but it's not good enough. This get's rid of any remaining negative taste. This filter does a bang up job of it. My water tastes perfect and I'm happy. Made in the U.S.A., how often do you see that? I will keep buying this filter as long as this company keeps making them. By the way, I encourage you to go to their website. I could have saved a few dollars, but oh well, I'll go back to it in six months. I'm not waiting so long this time.

Love these filters, I have 2 fur babies, one sheds like heck but since using these filters, hair not accumulating as much in the house.

I have a drinking water faucet installed on my RV kitchen sink, with a 2.5x10 carbon block filter. I usually replace my filter every year. I've tried high-end filters from Pentek and GE. They can be up to $45 for one filter. I decided to try this less expensive option. A filter could last 3 months or 3 years, depending on how much you use it, and the actual water quality. Through 6 months of summer camping season, my filter does not clog up, and works well. I have a separate whole-house 1-micron sediment filter, so this 0.5 micron filter doesn't have to work very hard. It seems like a waste to replace it with a fancy filter every year. So a less-expensive filter makes sense. I only require 0.5 micron, ANSI certification, and cyst removal. This filter fits the bill at only $19.

Everything is fine with the filter but gave it four stars due to the large amount of carbon that poured out of the filter when flushing it before putting in to service. I hahe bought many filters like this over the years and can not remember that much carbon coming out with other filters during the flush out period.

Water is much crisper than when I used my previous filter

Fits perfect

I am using this on an under-sink filter. I wanted filtration for my drinking and cooking water. I choose 0.5 micron filtration for the capability because, well, it's as good as you can get and because I occasionally use a a nasal irrigation kit without boiling the water and recently learned about the Cryptosporidium and Giardia risks from doing so. (This filters them out.). I was using a 3M Filtrate filter, which, when I could find them, cost 3x the cost of this one. This provides even better flow. The water comes out odorless and, providing iFilters is truthful, properly filtered.
