Human ingenuity and technological progress have given us excellent water filters to solve this problem. These items are a must-have for more and more houses each year. I realized their value a few years ago and by now I have studied many filters. From my viewpoint, the HomeMaster Reverse Osmosis Filter (TMAFC model) is in the list of the top filtering systems. For a complete comparison against other models, take a look at our Top Reverse Osmosis Water Filter Comparison page.

The Home Master TMAFC R.O. filter solves most problems you may encounter using traditional RO systems. Moreover, it’s wonderfully designed and is easy to install which makes it an ideal choice

What Makes a Good Water Filter?

When choosing an under sink reverse osmosis filter, you need to decide what things are important for you. Filtering impurities from the water is most important. All the RO systems on our site have good specifications for this. Personally, I consider efficiency and convenience of installation and usage to be important ones.

Filtering

The HomeMaster Reverse Osmosis Filter is efficient and highly rated. It removes up to 99% of all harmful chemicals, including arsenic, heavy metals, dissolved solids, etc. For additional information about RO systems take a look at our detailed description of the How Reverse Osmosis Works page or the Reverse Osmosis Wikipedia entry.

Easy Installation

The installation process is pretty simple, so you won’t need professional help. The color-coded tubing and detailed installation instructions, included in the package, will let any homeowner successfully handle the installation process.

Why Buy A Home Master TMAFC R.O. Filter?

The filters are built from high quality materials in the US and include improved components from years of experience. These filters are certified to NSF standards. All Home Master systems remove chloramine using powerful catalytic carbon filtration. This is a great advantage over common carbon filters that can’t remove the chemical completely. Chloramine is a set of chemical compounds made up of Chlorine and Ammonia. Chlorine or Chloramine is commonly added to water supplies to kill germs and make water safe to drink.

A more thorough list of water contaminants and what they do can be found on our Types of Water Contaminants Removed by Reverse Osmosis page.

The TMAFC model also prevents storage tank degradation by adding calcium and magnesium to the purified water. Storage tank degradation happens in most systems due to the acidity of water. These minerals change the pH level and reduce the deterioration. While doing a TDS (Total Dissolved Solids) test, make sure to include a test for the pH. The addition of calcium and magnesium also improve the taste of water.

The most useful features of the TMAFC filter are:

Pros of Home Master TMAFC RO Water Filter

Among the advantages of this filter I’d like to highlight that the TMAFC filter solves many problems traditional systems have. For example, the ‘canister filter housing’ design issue.

Entire Filter Replacement

The systems that use it require changing only filters while the filter housings cannot be replaced. These housings accumulate sediments, biofilm and different microorganisms that reduce filtering and purification.

The TMAFC model has an innovative filter design that may be called ‘all-in-one’. The filter is part of the housing making annual changes more efficient. Because you change the whole part (filter and housing), sediment and biofilm does not accumulate. The result is even better filtering and a better quality of water.

Reduces Waste Water

The practical design of the system includes flow restriction elements that help control pressure in the chamber. This regulates the purification progress and minimizes waste of water, which is a big problem for most water filters.

Addition of Minerals

Minerals are added after the RO filter to enhance the taste. Without minerals, many people report a “bland” taste.

Cons of Home Master TMAFC RO Water Filter

The filter is great for me, but some people may find certain features unacceptable. For example, when I wrote about the mineral input in this filter, I said it’s an advantage to add minerals in after everything is removed by the RO filter.

For some people the most important thing is zero Total Dissolved Solids (TDS). This filter does not give you a zero for this indicator, as the minerals affect the result of the test. If you are one of such people, then choose another model that will help you minimize TDS.

Most issues reported from owners of the TMAFC filtering systems are from incorrect installation and use of the filters. Make sure to read the instructions carefully and change the filters in time. In most cases, you’ll notice a decrease in water pressure which will alert you to change the filters.

Conclusion

The TMAFC RO system is one of the best on the market. It combines a pleasant design suitable for any kitchen, easy installation, convenient use and 99% water purification.

If you care about your family’s health and try to cope with the pollution of water, this filter is definitely one of the best for you.

The iSpring water filters are built in the US from top-quality materials. The iSpring RCC7 is a comprehensive water purifying system that holds the WQA Gold Seal certification for NSF standard 58. It features most effective filtering technology combined with an attractive design.

One doesn’t need to be an engineer or have some fancy tools in order to install this device quickly. The manufacturer provides a very detailed installation video and you can always get more tips from people who have already tried this system.

One of the reviewers has a marine aquarium and says this system is a must for everyone who shares this hobby. It produces RO water that is truly safe for any kind of fish as long as you mix in a sufficient amount of proper salt in it.

Cons of iSpring RCC7

No system is perfect, so even such a great reverse osmosis water filter like iSpring RCC7 has its cons. There used to be quite a few complaints about the leaks but in 2014 the manufacturer has revamped the construction completely and its quality increased as a result.

The only issues I’ve found so far by studying the reviews have to deal with people not understanding the instructions and therefore handling the installation correctly.

Conclusion

The iSpring RCC7 is not the only great RO water filter out there, but I believe it’s definitely one of the best. The filtering system is extremely efficient and carries the certificates necessary to prove it. It’s also extremely durable.

The designer faucet is a nice touch. It was this as well as the reasonable water efficiency rate that tipped the scales for me personally.

This page will cover the basics of reverse osmosis water filters and show the pros and cons of many popular brands along with links to these filters in the Amazon store.

For an in-depth discussion of RO, take a look at our How Does Reverse Osmosis Work? page. This page also discusses the different filter stages which is summarized below. Another good resource for getting familiar with how it works is Wikipedia – Reverse Osmosis.

Why Do I Want An RO Water Filter?

When looking for a R.O. water system, it is important to find a brand that is the best value for your budget. Reverse osmosis water filters remove hard to filter contaminants such as lead, mercury, arsenic, etc,

I hear you – the most important requirement is that it remove as many contaminants as possible.

You are in the right place – ANY reverse osmosis filter will remove more deadly particles than a faucet water filter or a pitcher water filter.

Our popular What Contaminants Are Removed By Reverse Osmosis page includes details for those shoppers who want more information.

The best water system layout would be a water softener at the entry to the home and then a RO filter wherever drinking water is needed. For comparisons of water softeners, take a look at our Best Water Softeners page.

Each brand provides its own features and with all the options out there it can be difficult to narrow down which are your best bets. All the units we review below have a separate chrome faucet. Capacity is shown in Gallons Per Day which is abbreviated as GPD.

What to Look For In a RO Filter

Number of Filter Stages

A good water reverse osmosis water filter will have at least 3 stages, such as these below:

1. Sediment Water Filter – To remove the larger particles.
2. ​Carbon Filter – To remove small particles and larger chemicals such as chlorine. There may be 1 or 2 carbon filters.
3. Reverse Osmosis Filter – This removes the smallest particles including heavy metals such as lead and mercury.

Warranty

​A good warranty means the company will stand behind their product.  The warranties on the reverse osmosis filters above are 1 year or more.

How Long Will a RO Filter Last?

Another question is how long will the filter last?  Although it depends upon the “dirtiness” of the water that is getting filtered, a large filter size means the filter will last longer because it will take longer to clog up. The filters shown above have long lasting filters.

Reverse Osmosis Water Filter Dimensions

Many of these filters have similar dimensions.  In some cases, the under-sink dimensions may be very tight so the dimensions shown above may help you choose the best reverse osmosis water filter.

Stage 1 – The Sediment Filter

Made of Melt Blown polypropylene, the sediment filter removes dirt, silt, rust and large sediments of up to 5 microns. This filter is crucial in removing sediments that would otherwise damage or plug up the more delicate filters that follow.

Stage 2 – The Carbon Filter

Chlorine, a common compound in water, will go through the sediment filter. More importantly, chlorine damages the reverse osmosis filter. So we need to filter that out before it gets to the RO membrane. That’s the job of the carbon filter which has slightly smaller holes than the sediment filter.

Chlorine also affects the taste and odor of water.  The carbon filter isolates chlorine, reduces the amount of lead and removes harmful bacteria such as Giardia and Cryptosporidium.

Stage 3 – The Reverse Osmosis Membrane

The Reverse Osmosis membrane handles the isolation of 99% of contaminants. This filter allows water to pass through and stops contaminants as small as 0.0001 microns.

Stage 4 – The Post Carbon Filter

The post carbon filter is the final stage of the water filter. This carbon filter will remove any remaining odor and improves the taste of the final drinking water.

What does Reverse Osmosis remove from water?

As mentioned earlier the process removes contaminants. These contaminants are both organic and inorganic impurities.

Common water contaminants include:

Reverse Osmosis systems also remove odor and bad taste.
