Cleaning-free filters, are made of many layers of polypropylene. The cleaning-free spa filters are white with a gray bottom and top.
No cleaning - No filter chemicals - Clearer bathing water. You will simply experience a clearer and cleaner water than with traditional lamella filters. This at an inexpensive price while the work effort regarding filter maintenance will be non-existent.
The cleaning-free filter from Sannra™ consists of spun plastic, porous polypropylene, (the same material used in pet bottles). The bath water is filtered each time it passes through the filter, with each layer capturing smaller and smaller particles. This is not a new filter, but these filters have been sold as "originals" in the US, Canada and Europe for Arctic, Astral and as an addition to Sundance Spas.
We have manufactured new bottom connections, so that we can deliver to many different brands of hot tubs. In recent years, we have sold a lot of this type of filter and people are generally very satisfied and buy the same filter again.
Should be changed every three months for normal bathing.
If you bathe often and frequently, the filter must be changed more often. If you use two filters, change them every 6 months, etc.
Never use flocculants (Clarifier, Bright&Clear, Gentle Clarifier) with these filters. The filters naturally remove small particles which, in turn, cause cloudy water.
Never flush spa filters with high pressure.
Do not use oil-based fragrances that clog all types of filters.
We recommend that you use an old clean filter for 24 hours after changing the water and cleaning the pipes. There are usually small particles in the new water and there may be residues from the pipe cleaning that will shorten the life of the filter.
General filtration capacity of different types of filters and spa filters:
Sand filters. Removes particles down to 30 - 40 microns
Washable polyester lamella filter. Removes particles down to 10-20 microns.
Non-cleaning polypropylene spa filters, Filters out particles down to 1-5 microns. Thus, this is the highest performing type of spa filter for spa water treatment in terms of filtration capacity. The result will be noticeable in the form of clearer and cleaner bathing water.
After 3 months of normal bathing, simply discard the spa filter and insert a new one. If your bath is equipped with two spa filters, change both after 5-6 months instead. With normal bathing, 4 spa filters are enough for about a year.
Never again do you have to wash dirty filters every two weeks to get them clean from dirt and grease! If you bathe often and frequently, the filter needs to be changed more often. As usual, it is extremely important to shower before bathing.
As mentioned, never use flocculants (Clarifier, Bright&Clear, Gentle Clarifier) with these filters. The filters naturally remove small particles that cause cloudy water without you having to pay extra for it. Also, don't use oil-based fragrances that unnecessarily clog all kinds of filters.
Are filter chemicals needed together with cleaning-free Spafilter from Sannra™?
The answer is no. You no longer need to buy chemicals to clean your spa filters. The money and time you used to spend on this unpleasant task can be used for other purposes in the future. Even your own time spent on filter cleaning, when using traditional lamella filters for hot tubs, can suddenly be spent on more pleasant and enjoyable activities.
Need for maintenance?
Basically no need at all.
The filters are made of spun plastic, polypropylene, which has been treated to be antibacterial. The manufacturing process can be likened to making cotton candy where thin strands are formed layer by layer. All these layers give the filter an accumulated very large 'surface area' that can absorb dirt. The same type of filter is used in mouth guards.
No cleaning, i.e. no filter washes and no filter chemicals. Just change the spa filter and you're done. It's quick and easy to get better, clearer water.
We recommend using an old rinsed filter for 24 hours after changing the water and cleaning the pipes.
There are usually small particles in the new water and there may be residues from the cleaning process that will shorten the life of the filter.
