Whole house water filters
A whole house water filter will improve the quality of your water throughout your entire home. In this respect, whole house filtration systems are superior to under-sink water filters or countertop filters that filter water only at a single point of use (e.g. kitchen tap).
Whole house water filters are also considered more cost-efficient and more convenient than point-of-use filters.
In this Whole House Water Filter Guide, we will analyse the top benefits of these systems, what you should look out for when buying one, and which whole house water filters are the best.
The Many Benefits of Whole House Water Filters
If you own a larger house or apartment, installing a whole house water filter is the best way to get filtered water in your entire home, at every water outlet. But this is not the only advantage of whole house water filters:
Complex filtration: With few exceptions, whole house water filters are multi-stage filters targeting many types of contaminants from chemical disinfectants to microbiological problems and heavy metals.
Cost-efficiency: If you would otherwise install more filters in your home (e.g. under-sink filter, shower filter, inline filter to protect water heater from lime-scale build-up, etc.), the combined initial costs and maintenance costs of your filters will be higher than simply purchasing a single system that will solve all your filtration problems.
Convenience: Convenience is another great advantage of whole house filtration systems. Since you’ll only be dealing with a single system, you can save time and money on installation and maintenance. You won’t have to keep track of so many filter replacements or search for compatible filter replacements, you won’t have to spend time on installing several different filter systems, instead you’ll need to focus on the maintenance of a single system.
Any disadvantages? Whole house water filters do have some disadvantages as well, namely the fact that they’re more difficult to install than under-sink filters, for example, and you’ll probably need the assistance of a plumber. The other possible disadvantage of whole house water filters is that they don’t allow for a more targeted filtration. Let’s say you’d like alkaline water in your kitchen, but not in your shower. A point-of-use filter would allow you to get different water quality at different outlets. With a whole house filter, you get the same water quality at every water outlet. You can customise the filtration efficiency/type for the entire system, but not for individual water outlets.
How to Choose a Whole House Water Filter
As with any water filter, the absolute first step before deciding on a particular type of filtration system is to assess the quality of your tap water to determine the types and levels of contaminants you have to remove. Once you are aware of the issues that need solving, you can start looking for filter systems that can help you deal with those issues.
Apart from water quality, here are other things to consider when choosing a whole house water filter:
Household size & water consumption
It is important to size your water filter to meet your daily water usage requirements. Most whole house water filters are designed to meet the needs of a family of four. If your household is larger than that, make sure to choose a unit that will be capable of producing large enough volumes of filtered water to meet the needs of your family.
Investment cost & maintenance costs
The initial purchase price is only one component of the cost of a water filter. Deciding on a water filter based purely on the purchase cost can be a bad investment, especially if replacement filters are very expensive, which would drive up the cost of maintenance.
Filter performance & durability
You may buy a whole house filter that is designed to reduce the contaminants you’ve detected in your tap water, but you should also look into how much of the contaminants it can reduce (is it 80% of chlorine or 99% ?). The better the filter, the better the water it produces.
Another aspect is filter durability. You may have found a whole house water filter whose filters are cheap to replace, but if you have to replace them every three months or even sooner, costs will add up. Find filters that are durable and have a long service life (at least 6 months).
Whole house water filters tend to be bulkier, especially those designed for larger households. Size can become a problem if you live in a small apartment, so make sure to size your unit accordingly.
Do You Really Need a Whole House Water Filter?
Whole house water filters are designed with larger households in mind. If you live in a small apartment, a whole house water filter may not be needed, especially if the quality of your water is not as compromised, or you need filtered water only for drinking and cooking purposes. In this case, a simple under-sink or counter-top filter would be more cost-efficient and would save you more space.
Best Whole House Water Filters at WaterFilterShop.co.uk
Our online water filter store brings you a wide selection of whole house water filters including single-stage or multi-stage systems from world-renowned water filter manufacturers like Watts, Ecopure, Pentek.
To help you find the best system, here is a selection of advanced whole house water filters designed for medium to large households:
This 2-stage system uses a 1 micron pleated cartridge with a high flow capacity and a Pentek Bituminous 5 Micron Carbon Block filter, which together are capable of removing chemical disinfectants and their by-products (e.g. chlorine, chloramine, THMs), volatile organic compounds, sediments, rust, lime-scale, lead dust and other particles over 1 micron in size.
Filters must be replaced every 12 to 18 month, depending on usage.
Ecopure filters are known to routinely use active ceramic filter media for an all-natural and thorough filtration. This Ecopure whole house filter system is no different and uses two filters, one of which is a patented active ceramics blend, which features 4 different types of ceramics. The other filter is a Watts 4.5 x 10 Inch 5 Micron Post Sediment Filter, which is needed to remove calcium and magnesium crystals produced by the main filter in its process of dealing with hard water issues.
Other than this, the Ecopure will also remove heavy metals, toxins, chemicals, bacteria (E-coli and Pseudomonas), and raises the pH level of water.
This whole house filter comes with 3 types of filters, each housed in separate filter housings: a 5 micron pleated sediment filter, a large active ceramics whole house filter, and a 5 micron carbon block filter. These filters make the system efficient at removing the following contaminants: chemicals, heavy metals, VOCs, fluoride, bacteria, suspended solids and other common water contaminants.
The filter life of the sediment filter and the carbon filter is between 6 to 12 months, while the large active ceramic filter can last up to 3 years.
The Osmio PRO-III Ultimate Whole House Water Filter System is another advanced whole house filter, which has the same configuration as the previous Osmio filter, except it contains a GAC and KDF Process Media Filter Cartridge, which can target pesticides, algae, fungi, chromium, mercury, and a host of other contaminants.
For those needing to reduce fluoride levels in smaller households, we recommend the Osmio EZFITPRO-400 Small Whole House Water Filter System, which contains activated alumina known for its fluoride removal properties.
Whole House Water Filter Guide Conclusion
Hopefully, you are now up-to-speed with the particularities of choosing a whole house filter, and you can make informed decisions about purchasing one for your home. If you want to combine filter technologies, you can use point-of-entry ultraviolet water sanitizers with your whole house system, especially if your need to deal with bacterial contamination issues. If you have the skills for it, you can even build your own filter system for an ultra-customised filtration.
Whole house water filters have very few drawbacks and are the most cost-efficient and convenient solution to having access to filtered water everywhere in your home.
