A shower filter passes incoming water through layers of filtering materials that remove contaminants. The process usually involves activated carbon or KDF (Kinetic Degradation Fluxion), which absorbs or converts chlorine, heavy metals, and other impurities. This results in cleaner, healthier water coming out of the shower head.
However, it is critical to ensure that a shower filter works. Here are the best ways to ensure that s shower filter works.
4 Ways to Test Shower Filter’s Effectiveness
Water Testing Kit
You can use a home water testing kit to check water quality before and after it has passed through the shower filter. These kits typically include strips that change color based on the presence of different contaminants such as chlorine, heavy metals, and bacteria. Compare the results from the pre-filtered and post-filtered water tests to assess the filter’s effectiveness.
For a more comprehensive analysis, you can collect pre-filtered and post-filtered water samples and send them to a water testing lab. These labs use sophisticated equipment to provide a detailed breakdown of the water’s contents, including trace minerals and potential contaminants. It’s more expensive but thoroughly evaluates the filter’s performance.
Visual and Sensory Inspection
Notice any changes in the water’s smell, taste, or color. A functioning shower filter should remove the smell of chlorine, reduce turbidity (cloudiness due to particles), and improve the overall sensory experience of the water. However, this method is quite subjective and doesn’t provide precise results.
Flow Rate Measurement
A significant decrease in the water flow rate can indicate a saturated filter that needs replacement. You can measure this by collecting the water in a bucket for a specific time and then comparing the quantity with the expected flow rate. This method doesn’t show the filter’s effectiveness in removing contaminants, but it helps indicate if the filter is clogged and needs maintenance.
Tips to Select the Best Shower Filter
Consider Contaminants: Understand the common contaminants in your local water supply. Choose a filter designed to remove these effectively depending on whether you have hard water, high chlorine, or other specific contaminants.
Filter Technology: Consider the filter technology used. Active carbon filters are effective against organic chemicals and chlorine, while KDF filters are good for heavy metals and sulfur. Some filters combine multiple technologies for broader filtration.
Filter Lifespan: Look for filters with a longer lifespan before needing replacement. This will save you both time and money in the long run. Manufacturers typically state this in gallons of water filtered.
Installation and Maintenance: Ensure the shower filter is easy to install and replace. Some filters can be fitted to your shower head, saving you from buying an entirely new unit.
Certifications: Check for certifications from independent bodies such as NSF International or the Water Quality Association. These confirm that the filter performs as the manufacturer claims.
Reviews and Ratings: Lastly, read user reviews and ratings. These can provide real-world insights into a product’s performance, longevity, and ease of use. Make sure to choose a highly-rated filter from a reputable manufacturer.
