FAQs

Will this filter remove 100% of the fluoride?

It will remove up to 93% of fluoride under the stated operating conditions. It is important to note that the media used to remove fluoride – activated alumina – is contact dependent. This means that by increasing the amount of time the water spends in the media, more of the contaminant will be removed. Operating the system at less than the maximum flow rate improves the contact time and increase the removal rate. Slow your flow!

Is Activated Alumina the same as Aluminum?

No, Activated Alumina is NOT the same as Aluminum.

--> Aluminum is an element with the symbol Al and atomic number 13. It is a silvery-white, soft, nonmagnetic, and ductile metal.

--> Aluminum oxide, on the other hand, is a compound with the formula Al2O3. It is a white crystalline solid. Activated alumina is not a good material from which to make hats.

In summary, aluminum is a metal, while aluminum oxide is a crystalline compound made from aluminum and oxygen.

Is the filter replaceable?

Yes, it contains a replaceable filter cartridge. Change it every 3 months or 500 gallons, whichever comes first. A wrench is not needed to open the housing. Replacement filter part number: CFF25-10

Can I test the filter performance with a TDS meter?

Not really. TDS is a measure of total dissolved solids - the bulk of which are calcium and magnesium minerals, which this filter leaves intact. As a result very little, if any, change in TDS is to be expected. A better option is to use chlorine test strips, and view that result as a surrogate indicator for the filter’s overall performance.

This cartridge does a great job of removing the chlorine that has been added to our city water (the lack of chloride taste speaks for itself). I haven't had our water analysed by a lab so as for the flouride that is added by our municipality, and other harmful components, I simply trust that these are being removed as much as possible (for such an affordable countertop system).

This is the upgraded filter to the other CFF25 model. I've used both but use this one for every day use ( I keep the cheaper CFF25 to use for filling water storage containers during hurricane season).This filter works well and I often filter it again when I fill my water filter pitcher ( Waterdrop Elfin) to make sure it's extra pure.When changing filters, the instructions say to run 5 gallons through the system before using but I've found that even at 5 straight gallons some discoloration still occurs. So here's what I do: Turn on the filter and allow the charcoal debris to run clear. Then:I SLOWLY run 3 gallons ( 12 16oz jars) then wait at least 10 minutes and run another gallon ( 4 jars) and then wait another 10 mins or more and run the final gallon through the system. This usually clears the water but just beware that when the filter is brand new, it may take running it for a few seconds before filling your glass to clear the light tan color. It's not as if it's toxic- just doesn't always look crystal clear right after those first 5 gallons.Highly recommend these filters.NOTE: One time I received a filter that was difficult to clear and it had orange particulate matter in the water. I contacted the company directly and they immediately shipped out a new filter at no charge. They explained to me that sometimes during shipping, the filter material can get disturbed. I've only had this happen once but this company has excellent customer service.

I've had this water system for about a year and it has worked great. Easy installation and the water definitely tastes cleaner. Where I live the tap water smells and tastes heavily chlorinated. In using the Home Master System to filter the water I can smell and taste the difference, no chlorine. Replacing the filter came with slight difficulty in that it took some effort to unscrew the cap from the bottom stand. However to me this means there is a good seal. I have never had any issue with leaks.

I bought the counter top unit from the manufacturer last year when Amazon ran out. I now buy the replacement filters from Amazon—the Home Master CFF2E-F10 Jr Elite Water Replacement Filter. It filters everything I don’t want in my water, including the combination of Chloramine.The filter life is six months, and during that time the water comes out chemical free and great tasting. I stopped buying bottled water, as this filter gives the same quality as commercial filtered water (my opinion). For the money it’s a great value and has saved me hundreds of dollars now that I don’t need water delivered. I highly recommend it.For aquarium owners, it’s known Chloramine kills fish, so while this filter may produce water safe enough for use in aquariums, do check with the manufacturer to be sure before you use it for that purpose.

We live in the country and have a cistern so have to haul water in. It's still city water and not the softest. Without the filter I found it had a chemical taste. This filter makes it taste so nice and clean and my coffee machine goes much longer without having buildup when using the filtered water.

way better than bottled water, or straight-from-tap water. One you use this, there is no turning back to the other - but then why would you. This filtered water is way better for your health

The photo on the left is the filtered water; the one on the right is tap water- the filtered water has a strange yellowish tinge. And yes I installed it the right way up and yes I let it run for 5 minutes after installing.Going back to my old brand....Update- after the customer service response, I let it run for a lot longer- 15 minutes and it did eventually become clear. I know another reviewer said that it had to be facing downward wouldn't work if the inlet/outlet was at the top, but I called customer service (very helpful) and they verified that it does not matter which way it is facing, as long as the right end is facing the inlet/outlet.The water is clear and tastes fine now. As I like to get quantifiable data- I am looking into testing the filtered water to see what levels of fluoride, copper and aluminum are.

I don't have overwhelming evidence that these filters that I've been buying for nearly 3 years are effective, so I'll mention the points of why I use this filtering system instead.I had been using a well-known "pitcher system" which requires buying filter after filter until I discovered that fluoride, which is a common additive in "town" water, plugs itself into the body's receptors meant for iodine. That alone was enough to warrant avoiding municipal water but I needed something better to remove the fluoride as Home Master purports to do along with chlorine and other chemicals.Since I use water kefir "grains" (assorted beneficial bacteria) to make my own probiotic I was buying spring water to avoid the chemicals that might kill my little guys. Even though I noticed no chlorine odor from Home Master-filtered water I made the switch to it for them gradually and now use it exclusively and add my own beneficial minerals instead. The fact that my little guys are doing just fine tells me that the filter is doing its job and I have the peace of mind that I've eliminated dangerous bromines from my water. Proof of the latter is that I no longer have an iodine-deficiency disease.I started with a counter top filter and then switched to an under-counter mount using their kit, along with a small stainless steel faucet in the hole in the sink provided for a sprayer, and couldn't be happier. I've improved the quality of my drinking and cooking water, no longer have to keep multiple filters on hand, and the little faucet at the sink is very convenient and much nicer than a bulky pitcher.
