Top 10 Best Washing Machine Filter – Review & Buying Guide

Do you live in an area where the hardness of water is on the higher side? If yes is your answer, it can probably show an adverse effect on your washing machine and your clothes. Hard water gets its hardness from dissolved minerals or salts, and it mainly contains a higher amount of calcium and magnesium.

These mineral salts can cause the limescale build-up inside the washing machine, and ultimately it reduces the life of your washing machine. Not only this but, it isn’t appropriate for your clothes as well because when hard water comes in contact with detergents, then it usually creates the residue film on clothes. Therefore, your clothes look dull and stiff even after washing multiple times, and you generally curse your washing machine for it.

And some manufacturers provide ordinary sediment filters, whereas some others provide a multi-stage filter.

The cartridge’s life span is something that matters a lot, and you shouldn’t ignore it while purchasing a water filter for washing machines.

Most of the time, you’ll find that the cartridge life span differs based on the washing machine type you have.
