RENTER FRIENDLY/EASY INSTALLATION – This single compact filter water filtration system fits under even the smallest sink cabinets—perfect for apartment dwellers. Measuring just under 15” in height and 3 1/2” in diameter, it can fit almost anywhere. Install right in the cold water supply line under sink, all of your cold water from the tap will be cleaner, fresher drinking water quality. The install kit contains 3/8” adapters to make connection easy in most homes (some older plumbing designs may require additional components).
CUTTING EDGE FILTRATION – This Advanced Technology water filter offers high level particulate reduction as well as chemical reduction including PFOA and PFAS. Particulate matter in water is very small, so small you typically can’t even see it! The physical structure of the HV-DWSP-FF filter media is so tight, it can remove particles smaller than 1 micron!
QUICK CONNECT FILTER DESIGN – Makes filter changes as easy as turning a doorknob. Just a 1/4 turn disengages the filter from the head assembly. Installing the replacement filter is just as easy! Replacement Filter is HV-DWSP-FFR. Also can use HV-DWSS-FFR.
NSF/ANSI CERTIFIED – HV-DWSP-FF is FULLY CERTIFIED by IAPMO R&T against NSF/ANSI Standard 42 for the reduction of particulate matter and chlorine taste and odor, NSF/ANSI Standard 401 for the reduction of trace pharmaceuticals and microplastics, and NSF/ANSI Standard 53 for the reduction of PFOA and PFAS, as well as Lead and waterborne Cysts like Cryptosporidium and Giardia. Be Careful! – Not all manufacturers carry full certification. Trust HYDROVOS for accurate and truthful certification information.

Easy installation – great taste
I haven’t tested the water with this, but it tastes great and has great flow. It was easy to install and reasonable price. Note to company- it was impossible to find this product using Amazon’s search. I had to find it using an external AI search tool using search criteria for NSF standards and enter the name in the Amazon search.

Best/most reasonable NSF 42/53 filter I could find
UPDATE: I had my original filter and I am on my 2nd replacement filter. The 1st 2 I used for about 6-7 months before changing. No issues at all and I will stick with this filter for the foreseeable future. Can be a little tough to get the cartridge out when replacing the cartridge and a little water might spill, but not too big of a dealI was looking for a reasonably priced water filter that was certified for more than just NSF/ANSI 42 (for chlorine). I also needed one that did not require a separate faucet. To be clear, this is NOT NSF certified, it is certified by IAPMO to meet NSF standards. This still seems to be a meaningful/reliable certification, but is cheaper for a company to do it this way instead of paying the NSF a ton of money. This filter is also certified to meet NSF 53 and 401 standards. I checked with the company about the plastic hoses they supply with the filter since plastic can leech chemicals (most filters I see use stainless steel). The company replied within a couple of hours and said that it is polyethylene that is tested by the NSF and tested against EPA requirements and approved for food contact. So I guess that’s good enough for me.The installation wasn’t bad. As others stated, the directions aren’t the best but no real issues for me. Make sure the blue hoses are pressed into the filter housing as much as you can. I initially had problems with it leaking but it stopped once I pushed the hoses in more. I didn’t use any Teflon plumbers tape on the connections.This filter is certified for 1651 gallons. This was the most I found for a comparable filter/price. (A lot fewer gallons than most NSF 42 only filters)I haven’t ran any testing on my water so hopefully it’s doing what it says. So far so good though, I’ll update if there are any significant changes.

It leaks within one month of installation
We purchased this undersink water filter because it reduces PFOS. We installed it over a month ago and was pretty uneventful easy installation. Now just one month later it has flooded our under sink cabinet and is leaking from the cap. There is no reason why it is doing this unless its a defective product. Very unhappy with this purchase.

Highly recommended if you want a hard-to-find NSF 401/53/42 kitchen sink filter
Rare NSF 401/53/42 drinking water faucet filter. Vast majority are not NSF 401/53/42 certified. My installation taps into the kitchen sink cold water supply, then filters that water to supply a special drinking water faucet. Both the filter and its dedicated faucet were very easy to install. No leaks at all. On general principles, I added 5-cent each blue locking clips to the push-to-connect fittings. Due to a complex kitchen sink plumbing environment, I connected the filter’s blue 3/8″ tubing to a braided 3/8″ compression supply line, the other 3/8″ compression end connecting to the cold water supply valve. For my ease, I also (optionally) inserted a small 3/8″ plastic valve. See the uploaded images. Excellent in all respects. Highly recommended if you want a hard-to-find NSF 401/53/42 kitchen sink filter. No leaks at all. No taste. No smell. Clear water. Excellent value.

The only reasonably priced filter that has 53 and 401 for most pollutants
NSF certifications 53 and 401 are granted per pollutant; for example, some filters only get certification 53 for Lead, but not for Arsenic. Most filters claim to have 53 cert but when you look on the NSF website they only have the cert for 1 or 2 pollutant. This filter gets great marks because it has the certifications for all of the important pollutants (you can search Hydrovos on NSF website or IPMO R&T website to prove this) but still has a reasonable price point. In addition, it has the PFAS cert from IPMO R&T which is unheard of at this price point.The install instructions aren’t great, but you can figure it out fairly quickly. My advice to the manufacturer would be to make a youtube video with install instructions, but quite frankly this is still the best undersink water filter out there.

Follow the instructions closely.
Easy to install, no leaks. Water is sparkling clear and the taste is good, but I will update this post as to its overall performance. I plan to compare the water quality of this filter to other sources within my home. So far, everything is good.The most important steps to a successful installation is cutting the water line straight (90) and pushing it into the filter completely until it locks. Also, if mounted leave space (3.5 in) below to change filters.
