Design and specifications may be updated in future production runs.
Keep your plunge water fresh without the faff of constant refills. The PortaPlunge Filter Only is a plug and play filtration system designed for new plungers who are using natural cold weather to chill their pool and simply need clean, circulating water.
This prototype filter kit partners perfectly with the PortaPlunge range and other above ground plunge or pool setups. It uses a 330 gallon ground pool cartridge filter pump to circulate, decontaminate and filter your water, helping to remove dust and debris from the bottom of the pool and keep your water clearer for longer.
The lightweight plastic housing is durable, reusable and easy to move into position. All key accessories are included, so you are not hunting around for extra fittings.
Just connect, plug in and plunge.
