Osmio PRO-III-XL Ultimate Whole House Water Filter System

Osmio PRO- III-XL Ultimate Whole House Water Filter System is the finest as the whole house water filter system to meet the needs. This is purposefully designed for removing a series of water impurities like toxins, chlorine, heavy metals, and more, and even for getting rid of the unpleasant odors and tastes possible to be there in the water supply.

The Pro – III comprises 3 filters and housing bowls. All the housing bowls are separated to ensure greater installation flexibility, in the L shape for placing into the corners.

The system has three filters with three separate housings. The filter configuration reads as –

Housing 1 – 4.5 x 20 Inches Black Housing with Active Ceramics Whole House Filter –

After every three years, the filter is replaced with 300,000 liters. It is effective to reduce and remove most impurities there in hormones, chlorine, lead, fluorine, and more. The highly advanced filter effectively kills the bacteria contained in water like E-coli, Pseudomonas, and similar microorganisms.

Using a unique filtration method, the filter makes use of the patented active ceramics blend. Thus, it is having four varied active ceramics treating the water differently and totally uniquely.

The filter helps in adding antioxidants, and minerals back to the water once water is filtered. Water becomes more alkaline with raised pH value – the pH value goes up to around 0.5 for each point – but it could be either more or less based on the number of certain variables, which include some dissolved solids and gasses.

Housing 2 – 4.5 x 20 Inches Black Housing with Carbon Block 5 Microns

This filter cuts down the chlorine. It reduces odor and taste issues likely to be present in the main tap water. Even the Volatile Organic Chemicals are reduced from the drinking water.
The carbon’s coconut base creates a little sweet taste that is sweeter. Having high dirt holding capacity, the carbon block has virtually zero pressure drop. Rated for 46,000 liters, the filters are changed after six months.

Housing 3 – 4.5 x 20 Inches Black Housing with KDF and GAC Process Media Filter Cartridge –

The cartridge is meant for primarily reducing the chlorine and chemicals’ bad taste and odors in the water. The filter has a Granular Activated Carbon GAC along with Kinetic Degradation Fluxion (KDF) Combining them, they effectively kill fungi and algae; control the growth of bacteria; eliminate pesticides, chlorine, rust, organic matter, hydrogen sulphide, mercury, calcium, cadmium, chromium, nickel, lead, iron; and remove unpleasant odors and tastes. The filter is perfect for the situation where a high flow rate is a must and the areas having issues with low water pressure.

The systems are supplied with a large housing spanner and brackets with screws.

The Eco – Advantage

As the water filter reaches its end of the main active ceramics cartridge, one can take the ceramics out and use it for fertilizing the garden to help improve the plants and grasses’ health as well as soil drainage. It is easy to put through the normal recycling waste.

 PRO-III-XL Ultimate Whole House Water Filter
