Can You Filter Bath Water, and Does a Bath Filter Work?

Yes, you can filter the water you wash in, and a filter that reduces chlorine is a worthwhile thing to have. The Flowpure shower filter reduces chlorine in shower water, which is the clearest and most honest reason to fit one. In my opinion, the best way to judge any filter is to ask what it is built to do and whether it does that one job well. This post covers what Australian sources say about chlorine, how to think about a bath filter, and why I would put a Flowpure filter on the wall.

Does a Bath Filter Actually Work?

A filter works when it does the specific job it claims, and the cleanest claim in this space is chlorine reduction. Flowpure states that its shower filter reduces chlorine in shower water, and I think that is a refreshingly plain promise. Plenty of products pile on long lists of benefits, but, in my opinion, one clear claim you can understand beats ten you cannot check. So, when someone asks whether a bath filter works, I turn the question around and ask what chlorine reduction is worth to you. If the answer is a shower you enjoy more, the Flowpure shower filter is the sensible place to start.

It could be argued that the shower is the best place to begin, simply because it is the part of the bathroom that tends to get daily use. That is only my view, but it makes sense to me that a filter fitted where the water runs every morning will be put to work far more often than anything that sits idle between baths. That being said, the same advice holds for every filter you might look at: buy it for a clear, stated purpose, and make sure the claim is one you can repeat in a single sentence.

Is Chlorinated Water Safe to Bathe In?

Central Coast Council in New South Wales states that tap water is safe for bathing, and it notes that chlorine is the most widely used disinfectant for drinking water in Australia and around the world. South Australia's SA Health says chlorinated and chloraminated water supplies are safe for people because only very small amounts are used. I take those statements at face value, and nothing here is meant to worry you. The point of a filter is different. Meeting standards and tasting clean are different things, and a filter is a way of choosing less chlorine in the water you use every day.

The Western Australian Department of Health explains that the Australian Drinking Water Guidelines say the level of chlorine in drinking water should not exceed 5 milligrams per litre. Having a number like that is useful, because it shows chlorine is a managed and measured part of the supply. Your own water supplier is the right place to ask what is in the water at your address. Knowing that chlorine is part of every glass and every shower, choosing to reduce it in the shower is a sensible step, and I think it is one worth taking.

Can Letting Water Stand Replace a Filter?

Busselton Water in Western Australia says chlorine taste can be removed simply by letting water stand in an open jug for a few hours. That is handy advice for a jug of drinking water, and it is a nice reminder that chlorine is something people notice. But, a running shower cannot sit in a jug, so the answer for the shower has to happen as the water flows. In my opinion, that is the gap a shower filter fills, because the Flowpure shower filter reduces chlorine in shower water as you wash. Standing a jug on the bench is a good habit for the kitchen, and a filter is the habit for the bathroom.

Why Choose the Flowpure Shower Filter?

I would choose the Flowpure shower filter because the promise is clear: it reduces chlorine in shower water. I like that it is one understandable benefit, and, in my opinion, that is exactly how a filter should be sold. It is a bit like buying a decent pair of sunglasses, where you do not want a long list of features, you want one job done well. Fitting a Flowpure filter is a small decision made once, and it works for you each time you turn the shower on. To my mind, having one in the bathroom is simply worth it.

What Should You Check Before Buying Any Filter?

Start with the claim, and make sure it is stated plainly for the exact product you are looking at. A filter that says it reduces chlorine in shower water gives you something concrete to hold it to, while vague promises give you nothing to check. Ask the seller to put the claim in writing, and be wary of any listing that cannot say what the product does in a single sentence. Then, if chlorine in your shower is what you want to reduce, choose the Flowpure shower filter, fit it, and enjoy the difference at the start of your day.
