What economic benefit does a homemade water filter have?
We present you the quick and concrete summary of how much you will save by investing in a reverse osmosis purifier that is the most recommended if you are in Mexico. (In a previous article we explained why, if you haven't read it, check it here).

Before knowing the annual savings, it is important that you consider:

1. What is the life span of the whole system?
A reverse osmosis water purifier has a useful life of approximately 12 to 15 years. 

2. How often are the cartridges of a reverse osmosis changed?
Ideally, the replacement of the reverse osmosis cartridges should be done every 12 months (except the membrane which is replaced every 2 years). This is to ensure that the reverse osmosis purifier works properly and is necessary for the membrane that is the most important (and most expensive) component of osmosis to maintain its useful life. If you don't, the contaminants will continue to be present in your drinking water.

3. Why should the cartridges in a homemade water filter be replaced?
First, the filters accumulate debris that can result in clogs that prevent the passage of water. Another domestic water purifier price in bd reason is that some types of filters (especially carbon-based filters) eventually lose their adsorption properties over time.

As a result, filters and cartridges need to be replaced regularly. Time and frequency may vary depending on usage, water quality, and water demand on the filter.  But to be safe and secure, every 12 months is a good time to replace the cartridges.

So if your filter has already been in use for a year, it's time for maintenance and replacements. Timely replacement of cartridges gives your reverse osmosis membrane a longer life and ensures that the water in your purifier is reliable.
