FAQ’s on Whole House Water Filter Systems

What health benefits does a whole house water filter system have for me and my family?

The main benefit of a whole house water filter system is the removal of chlorine from all the water in your home. Chlorine attacks organic compounds (people are organic) so it will dry your skin and also affect your airways. Chlorine is not dissolved in water and is given off as a gas so it will affect your skin as well as being inhaled.  Studies have suggested chlorine can aggravate respiratory problems (including asthma) and can irritate eczema-susceptible skin.

Another key benefit is the removal of particles which collect in the pipes that bring the water to your house. These particles can be rust, metals and sediment. 

Will the whole house water filter system soften my water?

No, the whole house water filters are not water softeners, do not either remove the calcium that causes hardness or add softening salts to the water.

Can I remove the water filter system if I move house?

Yes, you can move the whole house unit. The installation instructions are written so that you can move the system. We can advise you how to do this either when you are ready to move or before you install the unit.

Where is the water filter system placed in my home?

The whole house unit is normally placed where the water comes into your home. This is normally in a utility room or under the kitchen sink. If the mains water comes in under the sink it may be possible to divert the pipe if the unit can be placed in an area with more space. 

Can I install the whole house water filter system myself or do I need to employ a plumber?

The whole house water filter system can be installed by an experienced DIY person but it is probably best to get a plumber to install it. This is mainly due to the fact that the unit needs a bypass system and it can be awkward to find the best place to put it (and have access to change the filters).

We are a family of five with two bathrooms – what system would you recommend?

With that number of people and 2 bathrooms it is advisable to have a WH6 unit since it has the lowest pressure drop.

What chemicals does the heavy metal filter remove from the water supply?

The heavy metal filter is made to remove lead first. Once the lead has been removed then it will remove mercury and other heavy metals.

How long do the filters last? 

The filter will last anywhere from 6 months to one year depending on the water usage and the amount of contamination in the water. The best way to decide if the filter is spent is if you can smell chlorine in your shower or bath water indicating it is time to replace the filter. The Healthy House will send you a reminder when the filter needs changing.

Have the filters been independently tested and is this a good thing?

Yes, at The Healthy House® we believe we can only endorse our products if we are comfortable with their performances. Our drinking water and whole house water filtration products have all been independently tested. There are a number of third-party independent testing standards that our products may be covered by and these are:


If I have a whole house system, what should I install for drinking water and will it remove fluoride?

We usually recommend that you install a separate drinking water filter system.  The Ultracarb filter will remove bacteria, viruses and heavy metals. A single undersink unit will not remove fluoride, but if you install a double unit a fluoride filter can be placed in the first housing and an Ultracarb in the second housing.  Always check the specifications of the different filters. 

Are there any buildings/homes which cannot accommodate a whole house water system?

Yes, if there is insufficient room where the water comes into the building for example under the kitchen sink or in another particularly awkward and tight location.

Is there likely to be a drop in pressure once the filter has been installed?

Yes there will be a drop in pressure. The normal water pressure is 3.5 bar. A bar is 14pounds per square inch (psi) so normal pressure is 49 psi. With the standard WH3 unit the pre-filter will drop the pressure by 2psi and the carbon filter will drop the pressure by 9 psi so the total drop is 11 psi or about 0.8 bar. So the normal pressure will drop to 2.7 bar.

If your pressure is low you can use a WH6 which has 2 carbon filters which has a pressure drop of 4psi so the total drop is only 6 psi or 0.4 bar leaving the pressure at 3.1 bar. If you have a combi boiler or a megaflo system you do need a certain amount of pressure to activate your system. This varies depending on the system. If you have any questions about this please give us a call.

Can I use the whole house water filter system if I use a bore hole?

You can use the whole house unit with a bore hole but you will also need a UV filter to kill the viruses and bacteria in order to have clean safe water. Please give us a call to discuss your needs and for us to advise on sizing and other details.

Can you install one if you have a Quooker?

Yes it is a good idea to install a whole house filter since it will remove the chlorine from the water. The warmer your water is the faster the chlorine is given off as a gas. Therefore it is advisable to remove the chlorine so you are not breathing in the fumes.

How do I know what is in the water at home?

Many water suppliers provide a facility on their website to check the water quality in your area by postcode.   

How do I know which water filter system is right for me?

Please see our flow chart on the website which will guide you through the various options 

What is it really like to live in a house with a whole house water unit and a separate drinking water filter?

I think the first thing that you notice is that there is no aroma of chlorine and hands/body/hair do not feel dry from washing up or bathing.  Every cuppa has tasted better since it was installed and we have saved money by drinking our own water on the go (and taking it in our Healthy House glass bottles), instead of buying bottled water.  To be honest, it is also great peace of mind to know that the water at home is healthier for us with many impurities removed.
