How To Pick A Great Faucet Water Filter

I always been asked this question, what’s the best way to select a filter for my home without even seeing the product?

Well, it isn’t rocket science to differentiate which is junk and which is great. I always follow my own standard process of selecting any types of filter.

Here are some guideline on selecting a great faucet water filtration system.

Filtration Quality

I couldn’t stress more on this element. The quality of the filter is what makes the system great. No matter how technologically advance the system is, if the filtration quality is poor, then it is a bad filter.

One thing to note that, only compare to the system that is in the same class. It doesn’t make sense to compare the quality of a faucet water filter with an under sink reverse osmosis system.

Some sample questions that you could ask:

  • What are the contaminants that exist in my water source? Can this filter get rid of it?
  • How well the filter gets rid of the contaminants? What is the percentage?
  • How fine (micron rating) is the cartridge in filtering contaminants?

Cartridge Replacement / Lifespan

The lifespan of the cartridge always gives us a clue on the quality of it. The longer and larger the filtration capacity, the greater the system is.

Great cartridge means good technology has been used for filtration. Longer lifespan filter will decrease the yearly maintenance cost of the system.


The affordability not only on the initial investment cost. You have to factor in the subsequent maintenance cost of the system.

Some system has cheap initial cost while unaffordable maintenance cost. It is to trick customers into purchasing the system.

We break down the cost of the yearly maintenance in the above table for easy comparison.

Read The Reviews

Customer reviews often give you an insight on how well the system is performing. This can save you countless hours of returning the product and repurchase a new one to try it out.

Who Should Purchase Faucet Water Filter?

With the size and simplicity of design, this type of water filters are suitable for:

City Waters: Municipal treated water in urban areas tends to be less contaminated compared to well water source. Chlorine is the main contaminants. All of the systems are able to remove it.

Rented Apartment: Practically no hacking or huge installation needed for this type of system makes it a big fan among tenants.

College Students: They often opt for this option or water pitcher options as they are inexpensive system while still can provide some level of protection towards the contaminated water.

Small Kitchen: No tubing and the bulky canister will make your kitchen looks tidy. It free up some room for some other appliances.

Due to the small size of the system, the functionally and capability are often quite limited.

If you have a little more budget, you can opt for the countertop water filter which doesn’t require a lot of installation. It just needs some space near the sink.

Wrap Up

To conclude this, faucet-mounted filters are one of the affordable water treatment systems that are available for all. Check out our full drinking water filter guide for more options.
