Features of Under Sink Water Purifier

Under Sink Reverse Osmosis Water Filter System With 0.0001 Micron

With 5 stages under sink water purifier process, the filtration system can remove up to 99% of harmful contaminants such as heavy metals in the water, including heavy metals, chlorine, microplastics and other pollutants for safer and better tasting drinking water.


20 Micron pleated water filter replacement cartridge is fits most 10" filter housings for bench top, under-sink or whole house filtration system. Pre-filter for residential, commercial and industrial applications.


As the first line of defense in the filtration system, it can effectively prevent the clogging of water pipes and prolong the service life of water equipment.


Filters up to 15,000-20,000 gallons water.The filtered capacity and change-out cycle depends on inlet water quality or filters's running/using time every day. For better water quality, filters should be replaced regularly.


This filter can be washable for multiple times, but it's working effectively while the cartridge itself is not dirty, or following the change-out cycle we recommend to avert re-contamination of filtered water.

5 Stage Water Filter for Sink Reverse Osmosis Filter System

PP Sediment

PP Sediment holds dirt and prevents it from passing the under sink water filter system with clean water or process fluids. Also, as the first station of the reverse osmosis water filter system, it has a high dirt holding capacity and efficiency as it has a high surface area. Besides, the filter can work well under low pressure than other cartridges.

GAC Filter

GAC, a filter with granular activated carbon, is a proven option to remove certain chemicals, particularly organic chemicals, from water. As the second protector of the under sink water filter, it also can be used to remove chemicals that give objectionable odors or tastes to water such as hydrogen sulfide (rotten eggs odor) or chlorine.

CTO Filter

For an under sink water filter system, all carbon filters are rated for CTO (chlorine, taste, and odor) removal, and as a sub-micron carbon blocks, it can remove other contaminants like lead or cysts.

RO Membrane Filter

An reverse osmosis membrane filter has various filters that eliminate different types of impurities found in tap water through multiple stages of filtration. The most important part of these filters is the RO membrane. This membrane is a thin, semi-permeable layer that has minute pores on it to allow only pure water to pass through it.

Post-RO Carbon Filter

After water gets filtered through RO purification stage, another layer of carbon filter is added, called as Post-RO Carbon filter. Post-RO Carbon filter forms the last stage of the reverse osmosis water filter system. This carbon filter purification stage helps in improving the quality of the water.Post Carbon

Best Under Sink Water Filter System for Pollutants

This t1-5 is the best under sink water filter for most types of water impurities. As the untreated water passes through the GAC in the 5 stage under sink water filter system , chlorine molecules and many other contaminants get caught in the tiny pores, removing them from the water through a process called adsorption.

 Each stage of the reverse osmosis water filter system can remove a unique water pollutant. The pore size of RO membrane filter is around 0.0001 microns which is powerful enough to stop lead and many other harmful impurities, including sodium, chloride, copper, and chromium; can reduce arsenic, fluoride, radium, sulfate, calcium, magnesium, potassium, nitrate, and phosphorous. So if your house water is often polluted by among pollutants, this machine as an under sink water filter system for lead can be right choice.

Reasons You Need an Reverse Osmosis Water Filter

The reverse osmosis water filter are in need in many occasions where you might be unaware of. It can manage various types of polluted water. Home water with bad smell can cause nausea, headaches, delirium and convulsions.If your home water get with a light smell of rotten eggs, or sometimes get into odd colors, this is the time you choose a reverse osmosis water filter.

T1-5 ro water filter system adopts the best reverse osmosis filter that has tiny pores to preserve pollutants even like tiny bacteria. Within an eye blink, it can make your water into clear and pure. You can applied the water filter for sink as your daily water supply, protect your family from water pollution.

Best Reverse Osmosis Filter Without Electricity and Bump

This reverse osmosis water filter can work under normal home water pressure. It doesn't need electricity or bump, while it has high filtration precision at 0.0001 Micron. It saves much space and money in your home, provides your whole family daily water.

Under Sink Water Filter Installation in Few Easy Steps

Our under sink water filter is diy-able, with five filters set, you can change them based on your water condition. It can either connect to kitchen water supply or drinking water spply. When connect to your whole house water supply, the ro water filter system would require you to change the filter more frequently.

Washable 5 Stage RO Water Filter

The 5 stage ro water filter is washable, it works efficiently when the cartridge is in a clean condition. So it's better to clean it regularly, remove the plastic netting on some filters is necessary. Filters (particularly carbon-based ones) have plastic nettings to help keep the paper part of the filter in place. To clean the ro filter system, you need to remove that netting. Use a box cutter to slice around the edge of the netting at the top, just under the first ring. And follow the change-out cycle we recommend to avertre-contamination of filtered water.
