How Long Will A Whole House Water Filter Last?

If you are considering buying or have already bought a water filter for your whole house, you probably are wondering what are the maintenance costs, how much do they cost, and how frequently you should perform maintenance. On top of that, the biggest question is how long will a whole house water filter system last. While some users will install the system’s and forget about it, I wouldn’t suggest you do that, because it may be even dangerous to do that, because the components inside will degrade. Let’s start with some basics, and what will happen if you don’t change the filters within the system.

Think about it like this, your car’s air filter stops containments from getting into the engine to provide better performance, a water filter works in the same manner, it stops rust and other contaminants from passing to your house from the water supply, and just like in your car if you don’t change your car’s air filter you will definitely cause bigger problems. But it is not just that, as not maintaining your filters properly they will not work properly and you even risk contaminating your water. From the moment that the contaminated water passes from your water filters, it goes directly to your appliances, faucets, and showerheads, effectively decreasing their lifespan and the performance at the same time. So it would be counterintuitive to not change your whole house water filters.

A whole house water filter system often comes with two filters that will require you to replace them from time to time. The first one is the sediment pre-filter and the other one is a sub-micron post filter. Generally speaking, a sediment pre-filter has to be replaced twice annually or every six months, but it will depend on your water usage. On the other hand, a sub-micron filter has to be replaced annually.

I would suggest you have some spare filters in hand so you can swap them as soon as they need replacing or a problem occurs, so you do not compromise safety. It is worth stating that some filters may have optional parts such as UV filters, Water softeners, and even descalers, while these may all cost extra if you want better filtration against the one you should invest.

When it comes to the whole tank you can go without replacing for a long time, but you should still be careful, because for example if a tank has a rated life of 300,000 gallons of water, which roughly translates to 3 years of use, but it will also depend on your water usage, as the average number is for the average household.
