Every purchase decision that we make should be an informed one, and this holds true for water filter related purchases as well. Misconceptions and myths about water filters may prevent you from making the best decisions with respect to the brand, model, or filtration system. To help you avoid relying on myths and half-truths about whole house water filters, we’re going to debunk some common misconceptions about them.

Whole House  Filtration System, myth

Whole house water filters tend to be overlooked by consumers for a variety of reasons that have to do with their price, efficiency and maintenance. While some water filter brands or models may inadvertently enforce some of these misconceptions, most myths circulating about whole house filtration systems are completely unfounded.

Myth #1 All filters are the same

The diversity of water filter systems and water treatment solutions is a good counter argument against this misconception. Each filter system is specialised in dealing with a specific range of contaminants (e.g. ultraviolet water filters are good at eradicating bacteria, while carbon filters are know for their chemical removal properties), however, most whole house water treatment units combine different types of filter media to achieve a more thorough filtration. Different water filter brands or models have different combinations of these filters and design whole house water filters by taking into account the different needs of different households.

Myth #2 Whole house filters are expensive

Some models may indeed be expensive, however, a higher price tag is not necessarily correlated with a better efficiency or better quality. Whole house water filters are recognised as the most economical way to get filtered water in your home, and although point-of-use filtration units like kitchen water filters or shower filters may allow you to better customise the type of filtered water you need at each point of use, this possibility comes at a higher price tag – both the initial investment costs and maintenance costs may be higher than in the case of a whole house filter.

Myth #3 My house is too big, a whole house filter would not be efficient

No matter how big your house is, there is a whole house water filtration unit that can work for you. Specialist water filter stores can help you to choose the right filter size by taking into account the number of bathrooms you have, your water consumption and other factors. They can even help you construct customised filters.

Myth #4 Point-of-use filters are better

As mentioned in a previous point, point-of-use.filters may help you have a more targeted filtration, but the overall costs may be higher and you may need to spend more time on maintenance. It’s indisputable that point of use filters may be better for some households (e.g. small households) or for some individuals (e..g. people living in rentals or people who move a lot).

Myth #5 They need expert maintenance

Unless you’re buying a commercial filtration unit, water filter manufacturers have created models that are easy to maintain even by unskilled individuals. Thus, for example, quick-change filter cartridges make it easy to service your water filter even without the help of a specialist. Therefore, whole house water filter maintenance can be carried by virtually anyone.
