In recent years, home gardens have become more popular. A home organic garden gives homeowners control over what is going on with their food, but without a garden hose water filter, you are running a risk to you and your family’s health.

When it comes to gardening, you have to consider water quality. You do not want to expose your plants to chemicals. The point of watering is to nourish and hydrate your plants.

However, contaminated water reduces the quality of your crops and puts your health at risk. You can reduce the chemical load in your garden with the use of a garden hose water filter. Read on to find out more about the Top 11 Best Garden Hose Water Filters.

Why You Need a Garden Hose Water Filter

The water that comes from your garden hose is not safe for drinking. The garden hose water is the same as the water that comes through your tap but with some variation. Tap water is treated by a water treatment plant before sending it to your home. It also travels through pipes and fittings to prevent contamination.

On the other hand, the garden hose is not as safe as the pipes and fittings inside of your home. The garden hose is dirty and the material causes a reaction with the water. It is made from synthetic plastic, rubber, and web fibers to reinforce the hose. These materials make a water hose smooth and flexible.

Garden hoses can also be made with NSF International-listed polymers. However, a water hose is usually tested to prevent the polymers from leaking into your water. On the other hand, many garden hoses on the market are not tested for use with hot water. If you leave a pressurized and non-reinforced water hose in the sun for long periods, then it can burst. The rusty plumbing outside of your home also helps with contaminating your water.

What Kind of Chemicals are in Garden Hoses?

Several toxins can be present in PVC water hoses, such as lead, antimony, phthalates, and bromine. Some homeowners’ solution is to run the water hose for a few minutes before using it. However, it is still not a guarantee that the water is not contaminated after using this method. Here are some chemicals found in a water hose.


Bisphenol-A (BPA) is a chemical found in garden hoses. It is usually found in plastic wares. If you leave a water hose that contains BPA in the sun, then the material will react with the heat. This reaction results in the BPA getting into your water. People who drink water contaminated with BPA may see a rise in their blood pressure.

Lead is another chemical found in water hoses. This amount exceeds the standard set by the Safe Water Drinking Act. A tiny amount of lead is too much. It can be detrimental to your health.


Antimony is another chemical present in garden hoses. It can affect your health in a number of ways. Antimony exposure can cause liver problems, kidney failure, and other problems to your internal organs.


Phthalate is a chemical that is added to plastics and cosmetics. This chemical makes the product soft and flexible. It can affect your health in a number of ways.

Phthalates can damage your endocrine system, cause behavioral changes and lower your intelligence. It causes men to become sterile and cause hormones to become imbalanced. Many PVC garden hoses contain phthalates.

These toxins were found in PVC hoses. On the other hand, non-PVC hoses do not contain these chemicals. You also have to check the fixtures and connectors to the hose. The connector can cause contamination as well. You should check your connectors for rust and change them out for new connectors.

Pollutes Your Garden

The water that comes from your hose can affect your plants’ nutrition. Contaminated water changes the growing conditions of your plants. It can kill or harm your plants from chemical exposure. Water contamination can lower or raise the acidity of the environment. These growing conditions cause pollution in your garden. It is not something you want when trying to cultivate an organic garden with good plant nutrition.

Home gardeners should never minimize the effects of contaminated water. It not only affects your garden. Toxins like lead, BPA, phthalates, and antimony can contaminate the soil in your garden. These toxins can seep into the surrounding fruits, flowers, and plants.

Rain can cause the contaminated soil to run off to the street and into your water source. The contaminated soil can affect bodies of water and the animals that live in the water. If people are getting their tap water from the contaminated water source, then the people who drink the water become sick. Contaminated water affects your kids, pets, and livestock. It is a cycle that never ends.
