Filter, water filter, and above-ground pool

A filter, comprising:

• a filter cartridge comprising a side wall and an upper end;
• a cartridge cover disposed on the upper end of the filter cartridge;
• a first water distribution sheet disposed inside the filter cartridge, wherein the first water distribution sheet and the cartridge cover together define a first filter chamber;
• a second water distribution sheet disposed inside the filter cartridge, wherein the second water distribution sheet and the first water distribution sheet together define a second filter chamber;
• a fiber filter material disposed in the second filter chamber;
• a water intake channel in fluid communication with the first filter chamber;
• and
• a water discharge channel in fluid communication with the second filter chamber.

A water filter, comprising:

• a water pump, comprising a water inlet and a water outlet;
• a coarse filter cartridge in fluid communication with the water inlet of the water pump;
• a water filter cartridge comprising an upper end;
• a multi-position valve disposed at the upper end of the water filter cartridge, wherein the water filter cartridge is in fluid communication with the water outlet of the water pump via the multi-position valve;
• a fiber filter material disposed in the water filter cartridge;
• a water intake channel disposed on the coarse filter cartridge;
• and
• a water discharge channel disposed on the multi-position valve.

An above-ground pool, comprising:

• a side wall comprising a water inlet and a water outlet;
• a filter, the filter comprising:
• a filter cartridge, comprising a side wall and an upper end;
• a cartridge cover disposed on the upper end of the filter cartridge, the cartridge cover and the filter cartridge together defining a first chamber;
• a filter chamber disposed in the first chamber;
• a fiber filter material disposed in the filter chamber;
• a water intake channel disposed on one of the filter cartridge and the cartridge cover and in fluid communication with the filter chamber;
• and
• a water discharge channel in fluid communication with the filter chamber;
• a water intake pipe, comprising a first end in communication with the water outlet of the above-ground pool, and a second end in communication with the water intake channel of the filter;
• and
• a water discharge pipe, comprising a first end in communication with the water discharge channel of the filter, and a second end in communication with the water inlet of the above-ground pool.

An above-ground pool, comprising:

• a side wall comprising a water inlet and a water outlet;
• a filter, the filter comprising:
• a filter cartridge comprising a side wall and an upper end;
• a cartridge cover disposed on the upper end of the filter cartridge;
• a first water distribution sheet disposed inside the filter cartridge, wherein the first water distribution sheet and the cartridge cover together define a first filter chamber;
• a second water distribution sheet disposed inside the filter cartridge, wherein the second water distribution sheet and the first water distribution sheet together define a second filter chamber;
• a fiber filter material disposed in the second filter chamber;
• a water intake channel in fluid communication with the first filter chamber;
• and
• a water discharge channel in fluid communication with the second filter chamber;
• a water intake pipe, comprising a first end in communication with the water outlet of the above-ground pool, and a second end in communication with the water intake channel of the filter;
• and
• a water discharge pipe, comprising a first end in communication with the water discharge channel of the filter, and a second end in communication with the water inlet of the above-ground pool.

An above-ground pool comprising:

• a side wall comprising a water inlet and a water outlet;
• a water filter, the water filter comprising:
• a water pump, comprising a water inlet and a water outlet;
• a coarse filter cartridge in fluid communication with the water inlet of the water pump;
• a water filter cartridge comprising an upper end;
• a multi-position valve disposed at the upper end of the water filter cartridge, wherein the water filter cartridge is in fluid communication with the water outlet of the water pump via the multi-position valve;
• a fiber filter material disposed in the water filter cartridge;
• a water intake channel disposed on the coarse filter cartridge;
• and
• a water discharge channel disposed on the multi-position valve;
• a water intake pipe comprising a first end in communication with the water outlet of the above-ground pool, and a second end in communication with the water intake channel of the water filter;
• and
• a water discharge pipe comprising a first end in communication with the water discharge channel of the water filter and a second end in communication with the water inlet of the above-ground pool.
