What are the benefits of Miniwell L620 water filter?

1) Miniwell L620 protects us from the long-term and damaging effects dangerous chemicals such as chlorine have in our water. A Longer-Lasting Filter with High Effectiveness for Chlorine Removal.

Unique Carbon Fiber

Highly porous material provides a large surface area to which natural organic compounds, taste and odor compounds, chlorine can adsorb. 99% remove rate of Chlorine for 500L tap water

Miniwell L620 get all the taste and smell out of your tap water totally. Its removal efficiency of chlorine can be lasted much longer than other granular activated carbon.

Most other brands use granular carbon with visible black dust.

Carbon Fiber material with the longest cartridge life keeps 85% removal rate of chlorine after 500 Liters tap water filtration to 800 Liters. (Concentration of Chlorine in Tap Water is 0.9PPM in Guangzhou China) 

Other supplier carbon cartridge is granular activated carbon. Taste improvement lost in short term. Consumers can easily feel long lasting taste improvement of treated water from miniwell carton fiber.

2) 99.9% removal rate—Miniwell L620UF membrane has 0.1micron pore diameter that allows for the removal of all particulate matter, bacteria and colloids.

0.1micron UF membrane---How does it work?


Water naturally flows through the pores from the outside-in through the membrane wall under very low pressure. All germs and cysts are physically removed from the water.

UF Features:

1000Liter potable water with you on the go - Historically, the water separation process of ultrafiltration has been used in large municipal water treatment plants and hospitals; however through advances in technology, it is now available to you as a powerful portable filtration system in your backpack.

Chemicals Free—No chemicals such as chlorine, bromine or iodine are used for purification of water unlike other water purifiers, thereby making water safe and healthy for consumption.

Beneficial Minerals Kept—UF membrane does not remove any beneficial minerals in the water.

Wallet Friendly—UF membrane can be back flushed to extend lifespan. L620 UF filter outside-in configuration maximizes the ease of backwashing. UF membrane performance can maintain much more than 1000Liters if clearing is appropriate.

How often do I change my filter?
It depends on the quality of the water you are filtering. The more contaminated the water, the shorter the life of the filter. We suggest you replace it every 500Liters for best tasting water, for maximum effectiveness, the filter should be replaced after 1000L (or 12 months) of use.

How do I know its time to change the filter?
If you feel water flow slow down or can not sip water through filter, back flushing can improve its flow rate. If you feel flow rate very slow even through you repeat back flushing a couple of time, it is time to replace your filter.

What is the shelf life of my unused filters?
At least 5 years when stored in a cool and dry location.

The filter is designed for filtering tap water or natural renewable fresh water. Sugar, salt and other substances present in juices, tea and other beverages clog up the filter quickly and will damage it permanently.
