Notable Features:

This Apec 5 stage filter removes up to 99% of fluoride, heavy metals, bacteria, virus and 1000+ contaminants!

Includes a 1 year warranty automatically, however if you register you get the warranty extended to 2 years. Excellent customer service and response time and is also very responsive to questions and feedback on Amazon.

This system does exactly as it should, it cleans water extremely well leaving only clean good tasting water behind . This particular 5 stage system is not certified but uses certified parts, is from a reputable company, and it does the same thing the more expensive one does.

Since this Apec unit does not have the certification you save money and I am all about saving money.

If you prefer you can purchase the certified unit for an additional cost, but the quality is there already without the extra costs due to the certification .
