Should I filter the tap water?

Yes. Using the right water filter can help further reduce pollutants like lead from old water pipes, pesticide runoff in rural areas and byproducts of chemicals like chlorine that are used to treat drinking water.

Why drinking tap water is bad for you?

There are alarming levels of chromium-6 (the carcinogenic "Erin Brockovich" chemical) in drinking water that nearly 200 million Americans drink, from all 50 states.

Are faucet water filters worth it?

Faucet mount water filters are cheap, readily available at most grocery stores, and are fairly easy to install. Water filter faucets are great at taking out chlorine, and they aerate the water which makes it taste better.

No, the operating temperature of this water faucet filter is 41-122℉/ 5-50℃.

What is the ideal water pressure for this water filter faucet?

Operating Working Pressure: 15-58 psi / 100-400 kPa.(Normal water pressure for a house)

How often should I change my tap water faucet filter?

Up to 3 months or 320 gallons, which may vary depending on the feed water quality.

Do unused water filters expire?

The shelf life of an unused water filter is indefinite as long as its pouch is intact and sealed. We do recommend pre-soaking older filters in water for 15 minutes before using.

    Very easy to install. Every thing fit perfectly

    Everything fit perfectly previous different Named products came with too many attachments that just didn't work and made the task challenging. This is wonderful ??

    Great purchase

    Love this, we used to have to run the tap a long time to get water that wasn't cloudy looking. Now it's instant and tastes great. It was easy to install aside from the Teflon tape which I didn't really understand but it doesn't seem necessary either since I didn't end up using it. My cat seems to be drinking more water since we installed this as well.

    Happy with purchase

    Love it! Easy to install and works great!

    Idk, I guess it's ok

    Works ok, hard to tell if anything is actually be ring clean but I do drink from it

    Best on tap filter we've found!

    This thing is awesome! Not only does it NOT leak like ones we have bought in the past, even Brita.. But the pressure that comes out of it is really nice! We always thought it was a filter thing that would cause the water pressure to slow down but this really great.
    Would absolutely recommend this system. Oh the filters are really easy to replace too. And a good price.
