A Guide to Buying the Best Shower Filter

By Kealia Reynolds

The best shower filter removes harmful elements from your water, eliminates odors, improves skin and health benefits, and leaves you with an overall better shower experience. Not only will a shower filter reduce itchiness, dryness, and irritation, it’s an inexpensive option that allows you to filter shower water without having to install a house-wide water filtration system. We’ll go over important factors to consider before buying a shower filter and provide our picks for best shower filter.

How to find the best shower filter

Here are some factors that should be considered prior to purchase.

Type of shower filter

There are two types of shower filters that remove chlorine and other harmful materials from your water: Kinetic Degradation Fluxion (KDF) and vitamin C.

  1. KDF filtersKDF is a granular or fibrous combination of copper and zinc that generates a galvanic charge strong enough to convert chlorine into a harmless, soluble chloride. With a KDF filter, a positive and negative charge is created as water passes through the filter, trapping chlorine and other impurities in the water. These filters are most effective with hot water and can remove fungi and mildew buildup.
  2. Vitamin C shower filters—These filters are extremely effective at removing chlorine and chloramine (a combination of chlorine and ammonia) from your water. With a vitamin C filter, ascorbic acid reacts with chlorine to neutralize the water and make it cleaner.

What contaminants need to be reduced or removed from the water

All shower filters will either remove chlorine or reduce the amount of chemicals from the water that flows through your shower head. Some filters will also remove heavy metals, pesticides, and chloramine. Other filters will soften hard water by removing high levels of calcium and magnesium.


Filters typically last an average of six months (some shorter, some longer), but the actual longevity will depend on how many showers you take and how long they are.

Replacement filters

Before committing to a specific shower filter brand, ensure that you’ll be able to buy replacement filters for the product. If replacement filters aren’t available, you could end up paying for a brand new set every time the filter needs to be replaced.

Product and customer reviews

Reading product and customer reviews is extremely helpful when determining which shower filter is best. Read objective and third-party reviews to understand what each filter does and what it doesn’t do.
