Whether the water in your RV is not quite up to par, or you want to clean up your garden hose water, an inline hose filter will remove contaminants from your water supply before it even gets to the source.

If you’re a green thumb, the last thing you want is harsh chemicals like chlorine and chloramines covering your garden. Not only that but hoses are known to harbor bacteria and mold after sitting stagnant for extended periods of time. Many hoses, in fact, will even contain lead, BPA, and elevated levels of toxic compounds.

Likewise for RVs, when you’re on the road, having confidence in your water quality is critical. Hooking up and filling your water tank from different sources requires a treatment method to remove unwanted impurities.

The good news is that an inline hose water filter is a cheap and effective way to rid your water of these nasty contaminants!

What Will A Water Hose Filter Remove?

A quality water hose is capable of significantly reducing chlorine, chloramines, PFAS, lead, and more. Depending on whether you get your water from municipal suppliers or well water, your water contaminants will differ. If you have well water, synthetic fertilizers and pesticides can enter your water through irrigation runoff. Municipal water utilities almost always add chlorine and fluoride to the water, which is best not to be ingested.

Can You Filter Water From A Hose

Yes, you absolutely can filter water from a hose using a simple inline hose water filter. These types of filters easily attach to your garden hose or RV hose to treat water as it flows through the unit. Filtering water through a hose can remove over half of the harmful contaminants.

Hose Water Filter Buyer’s Guide

Now that we’ve rounded up some of the best inline hose water filters in the market, your choice will depend on several factors including your needs and budget. 

Key Considerations When Choosing A Hose Water Filter

Filter Material

If you’re looking for a hose water filter to remove chlorine, bad taste, and odors, an activated carbon filter will prove to be highly effective. Chlorine and chloramines can damage plants in your garden and upset the ecosystem. Using a filter with activated carbon is the best solution in that case.

Some carbon filters are now laced with copper or silver to further enhance the ability to kill bacteria and remove chlorine from the water.

A filter that is more suited for heavy sediment will also effectively eliminate large debris, sand, and dirt from your water supply. The Frizzlife or Camco are well suited for this use.

NSF Certifications

Although it isn’t a requirement, having the NSF certification indicates the filter is tested to the highest possible standards. The NSF website has a database you can search to see all NSF-certified filters. There are many specific certifications the filter can carry. For example, NSF/ANSI 42 is for the filter’s ability to reduce chlorine, tastes, and, odors. Whereas the NSF/ANSI 53 certification is for contaminants like lead.

Filter Replacement Life

It is important to factor in the replacement life of the filter when comparing your options. Some cheaper filters may look attractive but last only 1 or 2 months, so the replacement costs quickly add up. A good filter will last between 3 – 9 months, depending on your water use and the water contamination. The Frizzlife for example will last well over 3 months and you only need to replace the internal filter cartridge. This will not only save money, but it’s also echo friendly.


Inline hose water filters range between $20 and $75. The right filter will have to balance filtration performance and your budget. The good news is that most hose filters are a very cost-effective method to treat hose water compared to a whole filtration system solution.

How Do Inline Hose Water Filters Work

An inline filter is similar to most carbon-based water filters, the only difference being that it has a male and female hose thread on both ends. 

The male hose thread will allow you to attach the filter to a water source while the female hose thread will allow you to attach the filter to a hose. 

Once connected to the hose, water flows through the carbon media where impurities are absorbed into the porous carbon structure.

Benefits Of A Hose Water Filter

If you’re still on the fence about investing in a water hose filter for your garden, camper, or boat, here are some of the things that you could enjoy if you make that move:

Remove Harmful Contaminants Found In Water And The Hose

City water almost always contains chlorine, along with other harmful chemicals like PFAS, arsenic, and fluoride. But did you know that your hose can also contain very harmful chemicals like lead, BPA, antimony, and phthalates?

Even if the hose looks clean from the outside, these chemicals will contaminate your water even more.  When you invest in your own garden hose water filter, you reduce or remove these contaminants altogether, so you can have potable tap water to use for cooking, washing, cleaning, and gardening.

Enjoy Cleaner Water For Your RV.

Whether on a camping trip or on the road in your RV, clean water needs to be a priority.

With the right RV hose filter, you get to ensure that you are providing clean water that will help nurture the plants in your garden and is safe enough to drink and cook with. 

A good hose filter is also beneficial if you’re going on the road since you don’t know exactly the quality of the water that you’re getting from an unfamiliar source. By having a filter, you don’t need to worry about getting sick while you’re camping.

Reduce The Effects Of Hard Water

Hard water happens when there are too much amount of minerals like magnesium and calcium concentration in your water. When you water your plants with hard water, these minerals build up so plants don’t get the nutrients they need. 

If your plants are frail and small regularly watering them, could be because you have hard water. Fortunately, you can easily solve this problem by buying a garden hose water filter. This will reduce trace minerals in your water to make it more tolerable for your plants.

That said, filters are not specifically designed to tackle hard water. If scale build-up issues are plaguing your water, try a portable water softener instead.

Save A Lot Of Money

Investing in a simple water hose filter will help you save a lot of money as opposed to buying an elaborate water filtration system that will have a similar end result as your water hose filter. 

The right garden hose filter ensures you’re using good-quality water without breaking the bank. There are different kinds of water hose filters that will fit your budget, so you’ll have plenty of options to choose from.

Easy Installation

Unlike a water filtration system, you can easily install and remove a water hose filter without the need for tools. This is especially beneficial if you’re using the filter for your RV, camper, or boat where you’re always on the go and you’d want something portable and easy to manage.

What Can You Use An Inline Hose Water Filter For

Inline hose water filters have multiple use cases, which makes them a versatile treatment option to keep around the house. Using an inline filter guarantees endless fresh water for the following uses:

  • Organic gardening

Final Thoughts On Inline Hose Filters

Inline hose water filters are an effective and cheap way to get access to healthier water. Whether you need it for the garden, RV, or marine use, there is an ideal option for all uses.

Having the right filter means safer water for drinking and gardening. Quality inline filters can remove a majority of chlorine, lead, PFAS, and more.
