The type of filter that the pool is equipped with.

The filter is one of the most important types of equipment for swimming pools, including frame ones. It is responsible for cleaning water from dust, small specks and other contaminants. Considering that modern frame pools are quite capacious, it is easier, more convenient and cheaper to drive water through a filter than to change it entirely every time it gets dirty. Filters can be like this:

— Sandy. A device with a filter element in the form of a container containing fine sand of a special composition. During the passage of water, sand retains mechanical impurities, including rather small ones. One of the main advantages of sand filters is their high performance, they cope better with large volumes of water than another popular variety — cartridge systems (see below). In addition, filters of this type are reusable — if the sand is contaminated, nothing needs to be changed, it is enough to arrange a backwash. Among the disadvantages of this variety, one can note a relatively low filtration efficiency (including the inability to cope with chemical impurities), as well as large sizes. However, in many cases, the latter is not a disadvantage — the size of the filter is still small compared to the dimensions of the tank itself, and such a device is placed outside the pool, and you can choose the installation location so that the filter does not create any inconvenience.

— Cartridge. In accorda...nce with the name, these filters use special cartridges with filter elements in the form of membranes made of polymeric material. Cartridges are made disposable, with contamination and wear, such an element must be changed. This is associated with additional costs, but consumables are inexpensive, and initially cartridge filters are cheaper than sand filters. Another advantage is their relatively compact size. The speed of operation of cartridges is lower than that of sand systems, however, such a filter can still be made sufficiently performant even for a fairly large volume of water. Thanks to all this, most modern frame pools are equipped with cartridge devices.

Performance of the pump supplied with the pool (see above).

It refers to the amount of water that the unit can pump per hour. Knowing this amount and the volume of the pool (see above), you can estimate how long it will take to filter it.

Note that manufacturers usually choose the performance of a complete filter, based on the optimal compromise between good speed and low cost, as well as the weight of the unit itself. Therefore, in fact, this parameter may be required mainly in the case of searching for a replacement for the standard filter.

— Canopy. The presence of a canopy in the design of the pool. The main function of such a "roof" is to cover the people inside from the sun's rays. In addition, with the proper dimensions, the canopy can play the role of protection from the rain. Usually, canopies in modern frame pools are made removable.

— Staircase. Frame pools with sides from a height of 1 metre, usually, are equipped with special ladders. In the absence of the latter, getting in and out of the pool is quite inconvenient, and in some cases even traumatic. The user can always purchase the required ladder separately, but here it is worth paying attention to the fact that the ladders included with the pool are ideally adjusted to the height of the sides, which makes it more convenient and safe to use.

— Awning. The presence of an awning in the scope of delivery of the pool. An awning in this case means a “cover” made of fabric or other soft material, which can be used to cover the pool during non-working hours. Thanks to such a “lid”, leaves, insects, dust and other contaminants do not get into the water. Third-party devices can also be used to protect against debris, however, a complete awning, usually, is much more convenient: it optimally matches the dimensions of the pool, moreover, it is often equipped with devices for secure fastening.

— Bedding.... The presence of bedding in the scope of delivery of the pool. The main function of such a product is additional protection of the bottom from punctures: the litter covers small pebbles, twigs and other similar objects, due to which the probability of an “accident” is, if not eliminated, then at least significantly reduced. In addition, the pads are usually larger than the tank itself, go beyond its edges and can be used as an impromptu “rug” for swimming: for example, it is more convenient to take off your shoes before climbing into the pool and put on your shoes again on the pad, and not on the bare earth.
