Is Your Water Purifier Doing It’s Job?
Are you prone to forgetting when it is time to change the filters? We know the feeling!
Purlette engineers have developed an under-the-sink water filtration system that monitors the quality of your drinking water 24/7 and alerts you when the filter needs to be replaced. This latest generation smart home ready water purifier is simple to install and features a powerful and easy to maintain 2 filter hybrid system. The hybrid filter serves as the foundation of the Purlette system, housing the first three steps of filtering before allowing the water to move to the RO filter. Following a 5-layer 0.0001-micron reverse osmosis deep filtration step, the RO water returns to the Hybrid filter for the final step of post carbon block filtration. The result is freshness you can taste and see. On-demand filtration and tankless design eliminates the need for yearly water tank sanitation or hiring experts for simple tasks such as replacing filters. Purlette keeps your water clean, saves you time, money and space under the kitchen sink.

If WiFi is down, can the smart tech purifier still function?
Yes! The Purlette purifier will still function independently, as long as it is connected to the power and water supply. The system will continue to monitor water usage and information will be updated on the app when the network is back online.
How often Purlette filters need to be replaced?
The Purlette system will alert owner when a filter needs to be replaced based on the particular consumption habits of your household. User are recommended, on average, to replace the RO filter every 24 months and the hybrid filter every 12 months.
What can Purlette system remove from tap water?
Our 0.0001 μm five-layer reverse osmosis membrane removes up to 99% of total dissolved solids, including lead, cadmium and chromium III. Our patent-pending 4-in-1 Hybrid filter removes suspended particles, stops scaling, reduces flavor of chlorine.
Can I use Purlette for well water filtering?
The Purlette system is designed for the filtering of city water with a TDS level of less than 500. When using well water, the user must install a pre-treatment device on the cold water source and ensure the water source TDS level is below 500 TDS.
Can I connect the Purlette system to my refrigerator water supply line?
It is not recommended. Especially If the refrigerator already has a built-in water filter, the pressure force from the refrigerator filter element can interfere with the Purlette sensor and cause the Purlette system to turn on and off frequently.
