Four-stage, 36-Gallon per day Reverse Osmosis Water Purification System

Good things do indeed come in small packages, as the WECO TINY reverse osmosis water purification system is significantly smaller than standard filters and still delivers all of the benefits of the larger models.

Not only does TINY waste less water than standard Reverse Osmosis (RO) filters, no electricity is required for operation. The WECO TINY is the ideal filter for the home, as well as anywhere else safe, fresh-tasting water is needed.

The WECO TINY filter uses separate and individual stages of water filtration to create pure and refreshing drinking water:

Stage 1

The process starts by pre-filtering the water through a 5-micron filter. Prefiltration removes tiny particles that can get into the water supply. These include iron oxide (rust), silt, sand grains, and even insect biomatter. This stage prevents the filtration system from clogging, and more importantly, protects your family from drinking sediment. Best of all, no need to guess when the filter is full; the pre-filter housing is transparent, making it easy for you to see when the unit needs to be replaced. Remember that these filter cartridges are half the size of most RO filter unit components, making the unit compact and powerful.

Stage 2

The water flows through a 5-micron, activated carbon block cartridge. This compressed filter removes taste and odor-causing chemicals like hydrogen sulfide, eliminating that rotten egg smell and musky odors. Another important example is chlorine. The traditional chlorine disinfection process is known to create cancer-causing byproducts in the water. These carcinogens, called THMs, are removed by the activated carbon block filter. The cartridge also removes organic contaminants like herbicides, insecticides, and industrial chemicals that seep into groundwater.

Stage 3

The next filtration stage involves the reverse osmosis (RO) process. Tap water is forced through a special Thin Film Composite (TFC), semi-permeable membrane. Heavy metals, like lead, cadmium and mercury, are removed as the purified water passes through. The RO process also removes salts, nitrate, fluoride, radon, and benzene. The encapsulated RO membrane features outstanding water efficiency. Other RO filters can waste up to 10 gallons of water for every gallon of purified water. The WECO high-performance RO membrane produces only one gallon of waste water for each gallon of purified water! This saves you money, reduces waste water, conserves resources, and helps the environment. In addition, the housing makes it easy to replace the membrane when the need arises. No more complicated disassembly of the filtration system, no more leaks, and no tools required.

Stage 4

Lastly, the water flows through a Granular Activated Carbon (GAC), in-line post filter. This acts as a polishing filter, removing any traces of tastes, odors or gasses. The end result is crystal clear, fresh-tasting drinking water.

The WECO RO filtration system also includes a pressurized water storage tank and a brushed nickel designer faucet for dispensing the purified water. Both the storage tank and the faucet are also compact, further increasing the versatility of the TINY system. The faucets look attractive, fit in with any decor, and are certified lead-free to protect you, your family, and pets. As the filtration system makes purified water, it fills the storage tank. The storage tank sends purified water to the faucet. Your regular sink faucet will still provide unfiltered water for washing dishes and cleaning.

The WECO faucet provides only purified water for drinking, cooking, washing vegetables, and for pets. You’ll notice an immediate improvement in the taste of coffee, tea, iced drinks, fitness and sports drinks, and more! Even better than the taste is the peace of mind that you will have for you and those in your home.

The WECO filtration system is pre-assembled and can be installed with simple hand tools. Its ultra-small footprint allows installation just about anywhere - under-the-counter, bathroom, RV, boat. anywhere with sufficient water pressure.

  • The ultra-small footprint allows installation just about anywhere - under the counter, in a bathroom, an RV, boat, or anywhere else safe, fresh-tasting drinking water is needed.

Total Dissolved Solids (TDS) Content in Water

Why does TDS matter when it comes to water quality?

"TDS" stands for Total Dissolved Solids, which is a general measure of the amount of substances dissolved in lakes, streams and tap water. These “dissolved solids” include mostly inorganic salts like sodium, calcium, magnesium, potassium cations and chloride, bicarbonate, carbonate, phosphate, sulfate, and nitrate anions.

When water percolates through underground rock formations and soil, some of the natural minerals dissolve into the water. Depending on the amount and type of minerals in the rock and soil, the ground water could have very high or very low mineral content, or somewhere in between. Further, water treatment facilities sometimes add chemicals to prevent the water from being acidic or corrosive. The more substances dissolved in the water, the higher the TDS. This matters because the higher the TDS, the lower the purity of the water.

One the most useful functions of a TDS meter is the ability to check on the status of your WECO reverse osmosis (RO) filter. WECO RO filters lower the TDS by removing the minerals, salts, and contaminants from the water, increasing the water purity. The numbers don't lie, and a TDS meter shows just how powerful the WECO TINY filter truly is.
