Spot The Difference
Lets compare our filter media [Reemay] with that of another leading brand [for fear of being assaulted lets call it Media A].
Reemay Trilobal fibres deliver 67% greater surface area over Media A. Fused Fibres in Media A reduces effective filtration even further. (Both Media samples were micro-photographed at 900x on a black background from the same distance.
The spot-to-spot uniformity in this image of REEMAY versus MEDIA A is so apparent, it does not require explanation. BUT what does need clarifying is that Reemay has 42% greater void volume which results in DOUBLE the plug-time (clogging), therefore, it is twice the interval time between filter cleans.
Media Spot-to-Spot Uniformity - A critical property, whereby thin spots are weak links and result in dirtier spa water.
Media Unit Weight - Performance generally increases as the weight of the media increases.
Thickness -Creates both surface and depth filtration for optimum performance
Pleat Integrity or Rigidity -As media thickness is reduced, pleat rigidity is reduced; low pleat rigidity can result in pleat collapse
Filtration Efficiency -Correlates to turbidity reduction on one side, with pressure drop and filter life on the other
Filter Life -Optimum performance combines three related but different areas: dirt holding capacity, cleanability and media durability.
All Darlly filter cartridges are precision engineered and are built using Reemay media. Each cartridge carries a 12 Month Money-Back Guarantee, this is unrivalled in the industry and more than illustrates the confidence we have in our products
When buying a cheap filter is MORE expensive
There are plenty of cheap filters available in the Hot Tub market, sometimes 30% or even 50% cheaper.
These filters are cheaper because they use an alternative, cheaper media (the pleats).
These cheaper filters:
1) Cannot be washed and re-used
2) Will become 'blocked' and lose porosity very quickly. This will reuslt in a drop in water pressure coming from the jets and continual 'FLOW" error messages on your control panel because there is insufficient water flowing through the circulation pump. This will then result in a drop in heat and possible ceasure of the pump. A costly exercise.
3) Can collapse and become unusuable within 6 months. So you will need 4 filters instead of 1! Thus the cheap filters are probably TWICE as expensive.
4) Can release Phosphates from the bonding elements within the material. Phosphates are EXACTLY what the filter is supposed to be preventing. Phosphates are vital food for algae and bacteria, thus your spa water could become a health hazard and green in colour. An indicator of Phosphate is a Yellow FilterThank-you Darlly Europe
