Know what contaminants you want to reduce

For best effectiveness, of course you need to know what contaminants are in the water and which one you might want to get rid of them. Particular shower water filter can only work perfectly 100% in particular situation.

If you are wondering what contaminants may be in your water, you can start by getting a copy of your water quality report (called a CCR or consumer confident report) from your local water utility/authority (in the U.S. and some cities in Canada).

If you are unable to get your report or if you have a private well, you may want to consider having your water independently tested.

Get to know about 3 types of Shower Water Filter

Now that you have specified which contaminants to reduce, the next step is get to know about which type will fit your demand.

KDF (kinetic degradation fluxion) is a mixture of copper and zinc. When water flows through KDF, a tiny electrical charge is created. This electrical then charge forces free chlorine to combine with minerals in the water (usually calcium or another alkaline mineral). The combination of chlorine and these minerals is a harmless chloride.

Vitamin C: filters contain a block of Vitamin C (ascorbic acid). When the water runs through the filter, it will come into contacting with the Vitamin C. The Vitamin C neutralizes about 99% of the chlorine and chloramines in the water. Their effectiveness does not diminish until the Vitamin C is completely used up. You should use them for removing chlorine and chloramines from shower water.

Carbon removes impurities from water because of its sticky surface; it is normally excellent at removing chlorine. Carbon filter comes in many grades, but ahigh-gradee must be used if you want to take a shower with warm water. Carbon filter is primarily used for cold water. It is most effective at temperature ranging of 50-80 degrees (F). Therefore, at higher temperatures, carbon needs to be used as a second-stage filter. Moreover, it can be clogged easily.


– A small carbon filter cannot handle the volume of water that passes through a shower water filter. For carbon alone to work, the filter would need to be so big that it couldn’t be attached to your shower head. Once again, carbon can only be used as a second-stage filter.

– Don’t buy a filter that puts a carbon cartridge before a KDF cartridge. Activated carbon takes oxygen out of the water, but the KDF needs oxygen to work properly.

List out the extra qualities you want

Try to answer these common questions below to see if the product has met your need:

– Do I need a hand-held shower filter? Since it is more versatile and you can lift it out of the cradle to bring the spray close up to where in need, hand-held shower filter is suitable for children, seated showers, pets and cleaning tubs and shower stalls.

– How long  can it last? Nothing lasts forever, which is never wrong, at least to shower water filter. Generally, they can’t last over 6 months, or for some is 1 year without replacing filters.

How long it can last depends on the filter itself, and how long you shower. They can only filter a certain amount of water. If your shower time exceeds this number, you need to change your filter.

Pick the one that suit your bathroom’s devices and water’s condition

You should consider some special conditions of your bathroom and water when deciding which shower water filter to choose:

– Low water pressure: You should use a stationary shower filter rather than a hand-held shower filter.

– The height of the shower arm: Which is measured from the bottom of the tub or stall will determine whether a stationary or hand-held model is the most suitable. If your shower arm is relatively high, then a stationary model may be more appropriate, as a hand-held model may touch the ceiling and the extra height dissipate the power of the spray.

Vice versa, if your shower arm is medium or low, a hand-held model may be a better choice as it raises the height of the shower head – and makes it more convenient for tall people.

Is it easy to install or replace?

Nobody wants to waste time struggling on installing and replacing something minor like shower water filter. It is never too late to consider these questions before choosing a filter:

– Does it have replaceable cartridges? Okay, you have  to spend time  choosing wisely and now you figure it out than you need to buy a new one because there is no replaceable cartridge available. Oh come on!
