Why You Should Use A Bidet Seat Water Filter?

A bidet seat water filter can help your bidet function more properly. The bidet is actually a system of hoses and other kinds of pipes through which water flows. The water might contain impurities that might settle and build up over time. However, if you have a filter before the water can enter the bidet, then the filter will essentially remove all impurities such as calcium and sediment.

This will ensure no sediments build up inside the bidet over time or clog it. It will help to increase the lifespan of your expensive bidet toilet seat and bidet toilet combo.

Apart from that, bidet filter water is pure and does not irritate sensitive skin. Since you use a bidet to wash a very sensitive part of your body, you should ensure that the water is free of any irritants. That keeps the bidet water safe to use.

How to Install Bidet Water Filter?

Installing a Bidet Water Filter is quite easy. All you need to do is follow these steps:

  1. Simply attach the female end of the filter with the male end of the T-valve.
  2. Attach the other male end of the filter with the bidet hose.
  3. Turn the water on.

Hygiene for health is a consumer-centered brand who care for the needs of their customers. They have been in the bidet business for ages. However, they soon noticed that impurities in the water line were causing their bidets to leak and damage. So, they spent about 3 years researching a solution and finally came up with the best bidet water filter.

The bidet seat water filter meets all guidelines and is recommended by bidet manufacturers all over the world. The model is available in two types: ion and sediment water filter. The sediment water filter is for those who face a lot of particle impurities in their water supply, while the ion filter effectively removes minerals that might build up and result in impurities.

The Hygiene for Health filter fits a ½ inch fitting with a male and female connection at each end. The ion filter is quite nice as it adds negative ions and softens the water. It even captures particle matter. This filter has a huge capacity as it can purify 410 gallons of water or can be used for about 1500 flushes.

Living in a place where the water is loaded up with sediments can be a nightmare for your toilet appliance. Some people get their water from a well or through boring into the groundwater supply. Whatever the case, this water might be loaded with sediments.

Another one from Brondell, the SWF Swash Ecoseat bidet filter is the perfect companion for any Swash Ecoseat 100 model. However, we were disappointed to find out that it was not compatible with any other toilets, not even more Eco seats one.

This is basically a two-in-one filter that works as an ion filter as well as the particulate filter. The filter effectively removes all sizes of particles ranging from very small to very large. The ion filter inside works like a charm and effectively removes all calcium or other minerals.
