A true glass filter is the best swimming pool filter available on the market in 2016 for the following five reasons:
Ease of Use
The glass filter is basically a sand filter body with certified glass media inside the filter instead of sand. This means that the pool owner can backwash and rinse the filter just like they would a cheap sand filter. It is super easy and takes about 90 seconds to do!
Glass filters are the only filters on earth that currently carry the NSF-61 certification. This means that the glass filter can literally filter down to 2 microns AND capture Ecoli on the first pass! Even expensive DE filters can’t perform anywhere close to a glass filter when it comes to filtration. The only tricky thing is that there are lots of fake glass media on the market which are not NSF-61 certified so make sure that you are getting true NSF-61 certified glass media.
Unlike standard filters, a true glass filter only needs to be back washed once per month under normal conditions. This means a 75% reduction in the amount of water wasted each month! Pool owners love the time and water savings of this filter.
Low Relative Cost
The only filter that comes close to the filtration capabilities of a true glass filter is the DE filter which usually costs about twice as much as a true glass filter and is known for internal breakage issues.
Variable Speed Pump and Drinkable Pool Water Compatible
A true glass filter is fully compatible with a high efficiency variable speed pool pump AND with the “no salt no chlorine drinkable pool water systems” that have become so popular over the past few years. In fact, a drinkable pool water system requires that a certified glass filter be used as part of the system because no other filtration system is good enough to keep the pool water so clean that it is potable.
