Better safe than sorry, make sure to use filtered water when bathing.

Types of DIY Water Filtration Systems

When it comes to DIY water filtration systems, there are several options to consider depending on your needs and available materials. Let’s dive into some of the popular types of filtration systems that you can create at home.

Activated Carbon / Charcoal Filtration

One of the most common types of DIY water filters is the activated carbon or charcoal filter. Activated carbon is a highly porous material with a large surface area that can absorb a wide range of impurities from water.

We can create these filters using either store-bought activated carbon or making charcoal from wood ourselves.

These filters are especially effective at removing chlorine, odors, and improving the taste of water.


Sand and Gravel Water Filtration

Another simple yet effective method of water filtration is using sand and gravel layers. This type of filter works by forcing water through different layers of sand and gravel, which helps remove larger impurities and particles.

We can create a sand and gravel filter by cutting off the bottom of a plastic bottle, placing it upside down in a glass, and filling it with alternating layers of fine sand and coarse gravel.

This method might not remove all contaminants, but it’s a practical and low-cost option for basic filtration needs.

Fruit Peels To Filter Water
