FAQs on 4.5 x 10 water filters

What is a 10 x 4.5 water filter cartridge used for?

10x4.5 carbon filters are generally used for whole house applications, pre-filters for RO systems and other under sink filters, RV filters, and other filtration systems. They are typically used to reduce chemicals like chlorine taste and odor from your water.
Replacement frequency for your 10x4.5 carbon filter depends upon water quality, usage, media type, and several other factors. Typically you will want to replace every 6-12 months, or when you notice a significant decrease in water flow or a change in water taste and odor.
A 4.5x10 water filter will be compatible with 10” big blue filter housings. Big Blue is another term for 4.5” filters and housings started by Pentek that has become a common industry term. Alternatively they may be called 10” BB filters.
The micron rating you should choose for your 10x4.5 carbon cartridge depends on what degree of filtration you want, desired flow rate, contamination levels in water, media type, and more. For most whole house applications, a 1-5 micron carbon block and a 20 micron GAC filter should be adequate.
Carbon filters excel at reducing chlorine to improve taste and odor of drinking water. Carbon media adsorbs chlorine and other chemicals from water. Coconut shell carbon is particularly known for the improvement of taste and odor, and activated carbon provides enhanced adsorption of chemicals.
