CFS3 Pack Carbon Block Water Filter Cartridges Compatible with CBR2-10R, 155403-43, WHKF-DB2, WHKF-DB1, 34377 Models – Whole House Replacement Filter Cartridge – 1 Micron – 2.5" x 9.75"

Don't buy these filters. They do not meet the specs. They are too long causing leaks as the cap can't seal properly. I bought 2 sets with 3 in each pack. Had my plumber over today and 4 of the 6 don't fit. I'll just hit Lowes and pay full price vs. using these cheap knockoffs. Dont want to mess with water leaks on my kitchen floor. Very disappointed as other fridge filters i bought on Amazon work fine. These under the sink filters are worthless. Ridiculous!!!

second refill order, these are the best value at the time of ordering. filters out odor & taste of your tap water. can recommend

Matrikx make a good product.

Do a good job filtering drinking water from well.

Fits perfectly. Water tastes great!

The filter is in place, there is no expected decrease in water pressure. Does this mean that the filter is not working properly??? I can not taste chlorine that was there previously. I will continue to use these.

Giving the products a five star rating as a "I love it" comment seems a little odd. I did a follow up question to Complete Water Filtration Service and I received a prompt and complete reply.

Acabo de instalar el filtro. Cuando me lavé las manos sentí que la piel se cubría como de un aceite. Resulta que el agua sale del filtro turbia y aceitosa. Llené un vaso de agua y el agua está opaca. Este filtro debería ser prohibido. Viene de la India y en ese país seguramente los controles de calidad son mínimos.
