Not every household will need the same type of whole-house water filters. Even though all models have a similar working technique, the absence or presence of extra filters can hugely affect the type of contaminants that a specific filter will eradicate from the water. Here are a few things that you should consider irrespective of the number of filters that the system has.


Different filters will usually block different types of contaminants. Depending on your water test results, you should purchase a unit that effectively eliminates the contaminants that are present in your water. If your water has a high bacterial contamination, you will need a unit that has a UV filter. However, if you have a high concentration of heavy metal contamination, then a normal system with a copper-zinc mineral filter will be ideal.

Water flow

Different whole-house filters will produce varying amounts of filtered water every minute. Since all the water that enters your home must be filtered, this will be the same quantity of water that reaches your showers, faucets, toilets, and appliances. Smaller homes can easily manage with a filter that produces about 10 gallons of water per minute. However, larger households may not. You must ensure that you purchase a unit that is able to produce better water flow to suit the needs of your household.


When buying a whole-house water filter, you should consider the water consumption of your household. Choosing a cheap filter may seem like an excellent idea, but you may have to replace the filter often, especially if your home uses a lot of water. This will make the regular cheap filter changes more costly in the long run when compared to fewer changes of slightly costlier filters. Make sure that you balance the longevity of the filter and your household consumption when buying the right filter for your home.

Filter longevity

This is an essential feature because many whole house filter units will need little maintenance. One of the maintenance services that you will have to conduct regularly is changing the filters of your unit. The longevity of the filter will vary depending on the whole-house filtration unit that you settle for. You can settle for a 100,000-gallon filter or a 1,000,000-gallon filter for a similar filtration system. Always choose a unit that has a decent price and offers good longevity depending on your household consumption and water needs.


From your water testing results, you can choose the best micron ratings for your filters. The best filters will be able to block anything that is bigger than 0.35 microns. However, these filters tend to be more expensive than those that can only block particles that are bigger than 1 micron. If your home does not have a highly contaminated water source, then purchasing a 0.35-micron filter may be an overindulgence on your part.

A whole house water filtration system is a necessity for any home. Most people consider installing whole-house water filtration systems because of the quality of water they get. Even if you are connected to the municipal water supply, the water that gets to your faucet may not be of good quality. This is why you need a water filtration unit installed in your home to ensure that water entering the house is clean and pure.
