3M Aqua-Pure  : Detailed Review

The 3M Aqua-Pure water filter is one of the finest products you will find. It comes packed with loads of features. Before you think of investing in this unit, here is a sneak peek of the product details.

  • Contaminants Filtered

This water filter helps in reducing undissolved solids such as dirt and rust down to five microns. It can remove up to 90% of chemicals including residual chlorine that impacts the taste, smell and look of water. The water you get after the installation of this filter tastes great.

  • Flow Rate

Every filter has a specific time to filter water. To meet the needs of a household, the flow rate is measured in gallons per minute (GPM). The higher the GPM, the better it should be able to handle a household. For example, it takes 3 gallons per minute each for filling a coffee maker and taking a shower each takes 3 gallons per minute. In this case, this water filter has a flow rate of up to 10 to 20 gallons per minute which should be enough to meet everyone’s needs.

  • Micron Rating

Pores are measured in microns. They determine the largest size of the particle that can pass through a water filter. Filters that have a micron rating of less than five can get rid of more contaminants. This may include bacteria, viruses, etc. However, the flow rate is usually and cartridges can get clogged faster. You should use this type of filter only when you have a well.

On the other hand, water filters with large micron filters are not efficient enough as they cannot capture all the harmful microorganisms. However, they do have a vigorous flow. This water filter can remove particles down to five microns. Therefore, it is great to use with biologically safe water.

  • Scale Inhibition System

Minerals found in the water are good for our bodies. However, they don’t seem to have the same effect on your clothes or appliances. Too much of a mineral in water can damage both your appliances and clothes. Over time, they create a build-up that reduces water flow to your appliances.

But with this water filter, you don’t have to face any such thing. It has a scale inhibition system that doesn’t remove healthy minerals and also doesn’t use any salt. Along with that it also prevents limescale by preventing minerals from sticking to pipes. In areas where you are not allowed to use salt-based, this water filter seems to be the perfect alternative.

  • Life Span

The 3M Aqua-Pure water filter comes with steelhead and sturdy housing that is meant to last long. If you change the cartridge, it is going to give you a long service life. It has only one cartridge to replace. It is recommended to replace the cartridge once in a year and it will keep your water filter running like new.

  • Design and Installation

This water filter takes only twelve square inches. This makes an ideal choice for people living in small apartments or homes. As far as installation is concerned, it takes only one hour to get it installed.

Final Thoughts

From the above discussion, we know that the 3M Aqua-Pure water filter is a decent performer. It has all the important features you need. This water filter is ideal for small to medium-sized households. If you are looking for a reliable water filter, then this could be the one for you.
