Welcome to Darlly’s ‘How should I look after holiday park hot tub filters?’ topic.
Holiday park hot tubs require a higher level of maintenance, service and monitoring than your domestic hot tub. Looking after and properly maintaining holiday park hot tubs is beyond the scope of this topic. Today, we’re just discussing filters and the advantages and cost benefits of using quality filters.
Here at Darlly we recommend any commercial holiday let follow the guidelines of HSG 282.
How To clean and inspect your filter cartridges
The HSG282'S definition of a hot tub filter is listed below in italic.
Cartridge filter - A replaceable filter used in domestic-type spa pools and constructed from pleated paper or wound fibres, through which water is passed for filtration.
This paragraph is our recommended way of dealing with filters in a commercial setting. Remove the pleated filter cartridge and soak in a specific Cartridge Cleaner that is both acidic and a degreaser. This avoids the need for “Hosing off” with its attendant Legionella Risk from aerosolised water droplets. Gently wash off the Cartridge and then allow to dry. Hence the need for 2 sets of filter cartridges. NB: Do not use a pressure washer for this task and ensure that the power to the hot tub is turned off while the filter is removed from the hot tub. See also our topic ‘How to clean a hot tub filter’ in the ‘Filter care’ section of our website.
Top Tip: Given that it is necessary to allow a cleaned and rinsed filter to dry out before returning it to the hot tub, it is a good idea to buy a second set of spare filters so that whilst one set are being cleaned, rinsed, and dried, the second set can be in the hot tub filtering the water. This ensures that you do not have any downtime and you can still enjoy your hot tub whilst one set of filters are being cleaned.
As with most things in life, a high quality item can prove to be a more cost effective solution by being more efficient and having a long service life. A high-quality Darlly filter with durable and efficient filter material provides you with the quality water filtration that you and your customers demand and deserve.

Domestic-type spa pools – used as a business activity
76 Domestic-type spa pools or hot tubs used as part of a business activity (eg in a holiday park rental unit or hotel bedroom(s) with their own dedicated spa, or as part of a rental agreement for a single family or group use) are subject to the general duties under the HSW Act. There is a legal requirement for these systems to be managed and controlled in proportion to the risk and the risk assessment should consider the type of pool and its use. Domestic-type spa pools are for use by a small, discrete group of people at any one time and are typically:
- Of either a rigid or inflatable/foam-filled structure with freeboard and skimmer.
- Systems where the water should be changed after each rental/week, whichever is the shorter.
- Disinfected using bromine or chlorine through the use of an inline disinfectant feeder.
Filtration
95 Filtration is necessary to ensure adequate water clarity can be maintained through the removal of suspended particulate matter/debris in the water. Filtration is a means of entrapping particles mechanically and/or through absorption onto a filter medium. There are several types of system in common use and the choice of system type and size should reflect the anticipated type of use, circulation rate and bather load. Spa pools will typically only require one filtration system but multiple units and types in sequence may be appropriate, depending upon the local circumstances.
Cartridge filters – Cartridge filters are systems of tightly packed filter media such as fibreglass or paper in a demountable unit. They are small units and typically would only be used in domestic-type spa pools where the bather load and anticipated level of particulate matter was low. The design and installation should allow for removal of the cartridge for regular chemical cleaning, drying and periodic replacement.
