Replaceable Filters

You can buy this replaceable filter separately. The individual pack includes 3 of those each. As compared to buying packaged water, this faucet water filter is cost-effective. The filter has a built-in sensor that monitors and displays the usage levels of the filter. There is an indicator light on this unit that does the following.

  • The light turns green when the filter is working.
  • Turns yellow when the filter needs a replacement soon.
  • It turns red when the filter needs to be changed.


Something to keep in mind is that the sensor works on a non-replaceable battery. So when the battery runs out, the indicator light will stop working. You need to make sure to keep count of the period of filter usage after the battery dies so you can then replace it on time.

These filter cartridges are also not suitable for hot water. Running hot water through them will damage the purification system. Being aware of this will help sustain its filter life.

Purifier – Faucet Mount

Like all home appliances, it is important to know the ins and outs of your appliance, including its parts and terminologies. Knowing this will help during the installation process.

The purifier is the part that is bolted into your sink’s faucet with the help of a threaded connector. It contains a chamber that holds in the filtration cartridge. A flip switch is attached to the purifier. This flip switch controls the flow of water. Water can be directed through this flip either to the filtered part of the purifier or the tap. This system allows your filter cartridge to last longer.

You may turn the flip switch to tap water when doing the dishes and washing your hands. Turn it to the filtered waterside when you want to drink water. The purifier has a swivel capacity of 360 degrees around the faucet.

Faucet Connector

The Pur 3 stage water filtration system includes 4 different-sized faucet connectors. This helps in an easy fitting to the type of faucet you might have at home. One of the connectors is pure metal. This is a commonly used size as it prevents water from leaking.

The metal faucet connector may develop rust. This may damage the metal connector causing the water to leak.

The other 3 connectors are plastic. Plastic connectors are safe from rust which makes these durable. Yet, running hot water through it is a no-no here.


The Pur 3 stage filter is directly mounted to the faucet. This does not need any professional help or tools for installation.

Step 1: Select the size of the connector suitable for your faucet.

Step 2: Securely fasten the connector to the faucet.

Step 3: Fit the filtration cartridge into the purifier’s filter chamber and close the lid.

Step 4: Mount the purifier onto your faucet by screwing it to the connector that you installed.

Step 5: Turn the flip switch to the filtered-water side and let it run for about 3 minutes. This will activate the filter. (this step would be necessary while replacing the filter cartridge).
