Point of Use Systems
Point of use is the kitchen areas or any single area where water needs to be treated and dispensed. It is best to look at filter system 1) Whether an installed system is needed, and if so whether you want a stand alone dispensing tap or an integrated kitchen tap that provides filtered water and cold/hot (unfiltered).
Point of Entry Systems
Point of entry is where the water enters the property and before the water branches off around the property. These categories are for those who are looking to improve the water for showers, baths, heating and plumbing systems and more. It is worth noting that very good inline whole house filtration systems make water very good for drinking, but this is still many thousands of times less pure than reverse osmosis water filters (which are used only at point of use).
Frequently Asked Questions (FAQs)
Q: How do I know what type of system I need?
A: Choosing a filtration system to suit your needs might be overwhelming, but we have created range of comparison tables so you can choose system based on your property size and water quality requirements. The right system for you depends on several factors, for example the number of occupants and bathrooms is key, plus if you are needing an installed system, the space available to install. Use the comparison tables above to compare suitability against your water quality objectives. This will guide you to the right choice, but if you need more help, especially to check suitability or if you are not sure if it will fit, you can then reach out to us by phone 0330 113 7181 or Email to send us pictures/video of the install area.
Q: Do I need a separate drinking water filter if I get a whole house filter system?
A: The answer depends on your drinking water quality requirements. If you are looking for a scale free kettle or looking to replace bottled water, we suggest you look at our reverse osmosis water filter systems. These systems separate the water to a high pure and high concentrate streams making water at least 10,000 times purer than any inline point of use system and whole house filtration systems.
Q: So why get a whole house filter system?
A: When we bath and shower we absorb minerals, nutrients, and chemicals from water through the skin and into our bodies. Despite whole house filters being inline (and not reverse osmosis), they are capable of reducing chemicals (which are mainly gases), industrial solvents, pesticides, and aggressive chemicals that can contribute to irritation, dryness or itchiness. The very gold standard of home water quality would be a whole house filtration system followed by a softener if the water is hard, and then a reverse osmosis system in the kitchen at point of use. This is clearly all subject to your space and budget available. Simply contact us for any requests for assistance.
Q: My water is hard, can a filter make the water softer?
A: If you are in a hard water area you would need a dedicated water softening solution in order to tackle the limescale problem. Our whole house filter systems are for chemical, heavy metal, microbiological, and aesthetic potability parameters. Limescale (i.e. calcium, magnesium and bicarbonates) require either an ion-exchange salt-based softener or a more modern non salt water softener alternative. Salt-based softeners are going out of fashion, as consumers wake up to the fact they expel saltwater to the drain, which is a disaster for wastewater recycling, which is increasingly necessary as many parts of the country face water shortages in underground aquifers.
Q: Will I be able to get hold of replacements for the system I want in the future?
A: Yes, we make sure of that! Most of our systems use either standard or bespoke filters, but in every case, we ensure your continuity with us, and we aren't going anywhere! We are a healthy, ethical company with no loans or debts.
Q: Is it easy to install?
A: Getting the system installed is straightforward and requires basic plumbing skills. We use standard connections, all necessary materials can be purchased in local builders merchant so any competent DIYer can install a system. We recommend studying the product manual to assess your skills before attempting an installation. Getting everything up and running is only moderately difficult, however, if unsure - please invite a professional. Any plumber builder or handy person will be able to install our product.

If when inspected, goods are found to have been used, damaged or incomplete we reserve the right to refuse a refund or provide a partial refund.
Q: I tested your whole house system / undersink inline system / gravity system with a TDS meter, and it doesn't show a reduction, why is that?
A: TDS meters measure Total Dissolved Solids and is used to test the efficiency of reverse osmosis membranes. Outside of Reverse Osmosis, filters usually do not affect TDS in a significant manner. Typically, the largest portion of a TDS reading is composed of salts and minerals, such as calcium and magnesium. These are beneficial and ionising minerals. Your system works, it just isn't designed to remove these dissolved minerals. Instead, they target chemicals, heavy metals, microbiological and other parameters.
Q: What is TDS and what does a TDS Meter measure?
A: TDS stands for Total Dissolved Solids in water and comprises inorganic salts (principally calcium, magnesium, potassium, sodium, bicarbonates, chlorides, and sulphates), metals and some small amounts of organic matter that are dissolved in water. TDS level is determined by measuring the electric conductivity of the water sample. TDS levels can vary across UK regionally, and the variability of TDS has served as a very crude measure of water quality. In UK TDS typically varies from 150-350 and is dominated by minerals like calcium magnesium and sodium.
Q: Which parameters of water quality are not measured by TDS?
A: TDS is measuring content of charged compounds in water, uncharged impurities such as dissolved gasses (chlorine), oils, gasoline, pesticides, some pharmaceuticals do not affect TDS.
Q: Does a low TDS reading show I have low heavy metal, fluoride and bacteria content?
All these toxic impurities are charged when dissolved in water, however TDS meter can’t produce meaningful result about their concentration in water because TDS meter provides nonselective measurements and not designed to differentiate ions. Reading displayed on basic TDS meter is in parts per million, and impurities such a lead, fluoride are toxic in much lower concentration. For example, lead becomes toxic in concentration 20 parts per billion (1000 times lower). This means that water sample which has lead levels that are 100x the EPA limit, affecting the TDS reading only teetered between 000 and 001. More sophisticated equipment, operated by trained laboratory staff is required to perform those types of measurement.

Q: Are your filters recyclable?
A: It depends on the filter. All plastic encapsulated filters, including those for the Osmio Zero and D7 can be put into plastics recycling. Any filter that has granular media (such as carbon, KDF, active ceramics, can be emptied out and used for soil drainage and compost. Plastic components of those filters can be put into plastic recycling. Other types of filters such as melt-blown and bag filters are throw in the regular trash.
Q: Will the filter system reduce my water pressure or flow rate?
A: There will be a very minimal standing and flowing pressure loss. This can be a maximum of around 0.5 bar at full flow rate. If you have very low water pressure around 1.0 bar, we do not recommend installation of any point of entry treatment. We suggest a minimum incoming pressure of 1.5-2.0 bar to ensure satisfactory results. There is an inverse relationship between water quality and flow rate, so for drinking water, slower is better, meaning point of use systems can be regarded differently to point of entry systems. If you are unsure, just give us a call!
Q: How do I test my water pressure?
A: Use a pressure gauge which you can buy online or from any hardware shop or plumbers merchant. Please note there is a difference between standing pressure and flowing pressure. Standing water pressure can increase by up to 2 bar at night time when water usage goes low and standing pressure rises. It is therefore highly recommended to put a pressure reducing valve just after the stopcock at your home to protect all plumbing and appliances thereafter.
