Royal filter for the hot tub 175x152mm with thread (replacement for WELLIS hot tubs)

Filtration method via ROYAL FILTER:

Thanks to the perforated design of the body and the perforated central suction nozzle of the ROYAL FILTER, the water is drawn in all directions by the whirlpool pump through the Royal multifunctional microfiltration medium, which ensures thorough microfiltration from 3 microns.

Due to their robustness, the service life is estimated to be many years, only the multi-functional microfiltration medium is changed and this approximately once every 12 months.

Benefits of ROYAL FILTER:

• It is versatile and significantly saves the environment and especially your money!
• It provides thorough microfiltration of water from all particles from 3 microns in size, which is at least 10 times better than filtration through conventional cartridge filters or sand filtration. Safely filters out oils, grease, deodorants, antiperspirants, biological material, urea, and all particles invisible to the naked eye.
• Provides significant savings in money, water and cleaning time over conventional cartridge filters. Savings are a minimum of forty litres of water and 25 minutes of time per week cleaning of two conventional cartridge filters, and almost 100% savings in chemicals used to clean conventional cartridge filters.
• The Royal multi-functional filter media simply needs to be washed once a week in a washing machine without washing powder and fabric softener, in a quick programme of about 15 minutes at a temperature of about 35 degrees and left to dry freely.
• If you have iron or manganese in your water, the ROYAL FILTER will safely and effectively filter it out of your hot tub water without the addition of various chemicals.
• In combination with KYROL TC – a unique chlorine-free disinfectant and other chlorine-free hot tub water treatment components, it ensures clean and healthy water in your hot tub or swim spa.
• It guarantees a high water flow rate compared to commonly used conventional cartridge filters, thus significantly saving strain on the pumps and allowing you to make the most of their hydrotherapeutic performance. This is not always possible with conventional cartridge filters due to their poorer throughput caused by scale and sludge, which is also often the cause of pump failures.
• Thanks to the integrated skimmer at the bottom of the filter, it traps sediment and larger impurities that do not get back into the water in the whirlpool when the Royal multifunctional microfiltration medium is replaced, as is common with conventional cartridge filters. This guarantees minimal or cartridge filters, these will leave a great deal of debris that will simply wash out of the water when the filter is removed.
• The two components of the ROYAL FILTER – the ROYAL FILTER body and the ROYAL multi-functional microfiltration media are two separate parts and are fully recyclable.
• Cartridge filters have a maximum lifespan of one year, recycling cartridge filters can be a problem as two different materials are fixed together – plastic and filter cloth.

Cost comparison of ROYAL FILTER and Royal multifunctional microfiltration media compared to conventional cartridge filters.

The life of the ROYAL FILTER is virtually unlimited, but to see a realistic example of cost and savings, let’s calculate the average life of our hot tubs, which is 15 years.

The price of the ROYAL FILTER is 96,- € incl. VAT and the price of a regular cartridge filter is 48,- € incl. VAT.
The price of the Royal multifunctional microfiltration media is 30,- € incl. VAT.

The price of ROYAL FILTER together with Royal multifunctional microfiltration medium is 130,- € incl. VAT.

From the perspective of the first year, it seems that the cost of the Royal filter is 52,- € higher than the cost of a regular cartridge filter.

Now we divide the initial cost of the ROYAL filter as an investment over the 15 years mentioned, even though its lifetime is considerably higher.

96: 15 = 6.4,- € incl. VAT, which is the cost of the Royal filter for one year, if we count only 15 years, in reality it is at least once as much, thus saving once as much.

The price of ROYAL FILTER for one year is 6.4,- €.
The price of a regular cartridge filter for one year is 48,- €.
————————————————————————————
The saving in favour of ROYAL FILTER is therefore 41.6,- € per year!
————————————————————————————
However, from this saving we have to subtract the annual cost of 30,- € for the Royal multifunctional microfiltration medium.

By replacing a regular cartridge filter with a ROYAL filter and Royal multifunctional microfiltration media you will GET a direct annual saving of 11.3,- € for one filter, if your hot tub has two filters you will GET a direct annual saving of 20.6,- €, if it has three filters you will GET a saving of 34,- €.

In addition, however, you will GAIN very significant indirect savings on water consumption, your time, the consumption of chemicals for cleaning conventional filters, the consumption of chemicals for water treatment, and your hot tub water will be incomparably cleaner.

By replacing a conventional cartridge filter with a ROYAL filter and Royal multi-functional microfiltration media, you will GET direct annual savings depending on the number of filters in your hot tub:

• For one filter it is at least 12 hours of your time per year spent on cleaning a regular cartridge filter compared to the ROYAL FILTER, with the ROYAL FILTER you save at least 1000L of water per year, you also save at least 60,- € per year on chemicals used.
• If your hot tub has two regular cartridge filters you will get double savings in time, water and money, i.e. at least 24 hours per year that you would have spent cleaning the filters, for the environment you will save at least 2000L of water per year and at least 110,- € for chemicals.
• If your hot tub has three regular cartridge filters you will get up to three times the time, water and money savings, i.e. at least 36 hours per year that you would spend cleaning the filters, for the environment you will save at least 3000L of water and chemistry per year for at least 160,- €.

Normally whirlpools have two cartridge filters and by replacing them with ROYAL FILTERS you will directly and indirectly save at least 360,- € per year.

Your investment in a ROYAL FILTER always pays off and returns many times over.

You will have wonderfully clean water in your hot tub or swim spa, you save the environment and if your hot tub has two filters you SAVE at least 360,- € per year.
