Does this filter need to be flushed?
You’ll have to flush the new filter for 5 minutes to condition it.
Does this filter cartridge replacement require gaskets?
Gaskets are not essential for this specific filter. The filter’s soft end caps establish a good sealing when the filter is being pressed down by the housing cover/lid while you are tightening it.
When should I replace the filter?
It is recommended to change the filter every 6-12 months or when water taste changes or water flow reduces significantly it’s probably time to replace the filter.
Should I turn off the water valve when I change the filter?
Yes, please shut off the water supply before you change the filter.

Great Filtration Capacity: PUREPLUS CTO20BB filter reduces up to 99% of Chlorine, sand, rust, sediment, taste, and color. This kind of filter is recommended for tap water filtration. If your water source is well water, this filter may not achieve the filtering effect you expect. Check out our other product.
Ultra-High Quality Filtration: Carbon is well known for its unique absorbing ability, a pound of carbon is able to provide up to 125 acres of filtering surface area. Our whole house carbon filter is made of 100% coconut shell-activated carbon block to filter most sediments. Innovative sintering technology ensures high absorbing capacity and offers a much finer filtration of suspended particles and dirt.
Carefully Selected Superior Materials: Our filters are produced under the ISO9001 standard and inspected under strict quality control. Each filter is produced through 34 production processes, 400PSI pressure tests, 10,000 water hammer tests, and 6 independent tests.
Long-term Use & Protection: The filter can filter up to 100,000 gallons depending on water quality. Suggest replacing it every 6-12 months for the average household for optimal performance depending on the use. Let it bring a wonderful cleaner water experience to your loved ones.

Water taste much better
Use this as a replacement for my Watts whole house filtration system. It is working well and our water taste better than a different type of filter I tried. So far so good and will definitely purchase again if it holds up.

Great filter
This filter does a magnificent job of cleaning the water! I just hope it lasts as long as the last one we installed (different number).

Going back to Pentek.
Really decent company to deal with, I had a little issue, and it was corrected immediately. Great customer service, super fast service.

Solid fit and construction. Hope it takes the metals out
This filter is heavy duty so assume it works but haven’t tested the water. I have a Viqua 20” water canister and fits well. Just make sure you remove the old washers from old filter and ensure this filter’s washers are properly fitted. I would buy if you’re concerned with metals.

Charcoal filter working for my needs.
Carbon filter seems to be working for my needs as we have city water but with very high levels of chlorine. The first filter came broken so returned and repurchased. I am hoping that will last a while (6 months+) as these are not cheap. It is my 3rd stage filter with a 50 micron first, seconds a 5 micron and this one being the last one. I am providing a picture of the before and after installation as all my spoons and utensils looked horrible and needed to be rewashed and dried right away.

Perfect fit and quality looks great will have to add to that at the end of a full tear when it needs replacing
James Camilleri –
i bought this product, i didn’t need to use until my old filters needed changing. When i opened it to replace filter, it fell into 2 pieces as photos provided. it was always in a safe box in the garage so it must have happened in transit or at the manufacturers. i just want it replaced
