    Advantages of ROYAL filters

    • 1

      Due to their robustness, the service life is estimated for many years, only the multifunctional microfiltration medium is changed, approximately once every 12 months.

    • 2

      Royal filter is universal and significantly saves the environment and especially your money!

    • 3

      It ensures thorough microfiltration of water from all particles of 3 microns in size, which is at least 10 times better than filtration through conventional cartridge filters or sand filtration. It safely filters oils, fats, deodorants, antiperspirants, biological material, urea and all particles invisible to the naked eye from the water.

    • 4

      It provides a significant saving of money, water and time spent on cleaning, compared to conventional cartridge filters. The saving is at least forty liters of water and 25 minutes of time for one weekly cleaning of two common cartridge filters and almost 100% - saving of chemicals used to clean common cartridge filters.

    • 5

      Royal multifunctional filter medium is simply washed once a week in the washing machine without washing powder and fabric softener, in a fast approx. 15-minute program at a temperature of approx. 35 degrees and put back into the filters and whirlpool or let it dry freely.

    • 6

      If you have iron or manganese in the water, the ROYAL filter will safely and effectively filter it out of the water in the hot tub without adding various chemicals.

    • 7

      In cooperation with KYROL TC – a unique chlorine-free disinfectant and other components, chlorine-free water treatment in the hot tub ensures clean and healthy water in your hot tub or swim spa.

    • 8

      It guarantees a high water flow compared to commonly used classic cartridge filters, which significantly saves the strain on the pumps and you can also make maximum use of their hydrotherapeutic performance. This is not always possible with commonly used classic cartridge filters due to their poor permeability caused by scale and water sludge, which is also often the cause of pump failures.

    • 9

      Thanks to the integrated sludge trap in the lower part of the filter, it captures sediment and larger impurities, which do not get back into the water in the hot tub when replacing the Royal multifunctional microfiltration medium, as is common with classic cartridge filters. This is guaranteed at least with a cartridge filter, which leave behind a lot of dirt when removing the filter, which is simply washed away when removed from the water.

    • 10

      Both components of the ROYAL FILTER – the body of the ROYAL FILTER and the Royal multifunctional microfiltration medium are two separate parts and are fully recyclable.

    • 11

      The service life of cartridge filters is a maximum of one year, recycling cartridge filters can be a problem, as two different materials – plastic and filter cloth – are firmly connected. Royal filters can be fully recycled.

    You ask, we answer - F.A.Q

    We answer basic questions collected from our customers.

    Yes, it is suitable for any hot tubs or whirlpools.

    When choosing right filter for you, we can assist you and check the dimensions of the original filter and then recommend which filter to buy.

    If we don’t have the filter, we can custom-make it according to the dimensions of the original cartridge, which you can send to us by email or whatsapp on phone number +420 702 908 905 / +421 911 924 841

    On this page, we thoroughly explained the measuring of original cartridge filter: How to measure filter

    We will make a custom-made filter within 5 working days. We will inform you about progress in all cases.

    Each filter requires a different amount of balls, that’s why we prepared 4 sizes. The recommended size is always indicated in the details of individual filter.

    There are always a few extra balls in each package in case you lose one while cleaning or in case your pet decides to have a new toy 🙂

    The Royal Filter has a lifespan of at least 1 year. We recommend replacing the medium after reaching this time. It will be visible on quality of micro-filtration medium.

    We recommend cleaning the balls based on their contamination. On average, you should clean the balls once a week. Of course it depends on how often is the hot tub or whirlpool used, children etc.

     

    The microfilter medium contains 3 types of balls:

    • Black with black carbon fibers for odor absorption
    • Silver with silver fibers for better disinfection
    • White for pollution indication (after pollution, they will have a yellow color)

    The Royal Filter is our product, we did not copy it anywhere, therefore it had to undergo thorough testing on expensive devices and underwent significant changes in design and construction.

    We guarantee that the filter will fit your device. In case of any issues, we will make sure to solve them as quickly as possible. We like to help as much as we can in solving our customers water maintenance problems. We greatly appreciate your support and with your contribution we will continue developing Royal Filter and making sure for further improvements.

    “Absolute satisfaction. I was buying filters for a hot tub. Very nice approach and willingness to explain everything exceeded my expectations. Many to seller. Otherwise, the Royal filters are 100%. They really cannot be compared with a cartridge filter. Great satisfaction for me. I will gladly contact this store next time.!”

    “Great attitude, excellent and fast negotiations. The gentleman is willing, we discussed all the options over the phone and finally I decided on one. The goods were delivered within 2 days. Unfortunately, I didn't have the exact dimensions of the filter, but the gentleman immediately accepted the possibility that after specifying the dimensions, he would send a new thread so that it would fit into the hot tub. Great, great, great... I can only recommend.”

    We are VERY satisfied with this store. After buying a foam hot tub, we ended up with cloudy water after a week despite all the water purification with the supplied filter. We came across the Royal filter on the Internet. We were surprised by the friendliness, expertise and willingness with which they attended to us here. According to the photos, they made a tailor-made filter, advised on the choice of chlorine-free chemistry, and all this at a good price. The matter did not end for the company by processing the order (almost instantly). They were willing to continue to solve minor problems with us, mainly caused by our inexperience. We thank you once again and we believe that the commitment with which the local people work will last them well into the future.
