  1. For pools between 5,500-9,500 gallons
  2. Filter is 16” in height

We already mentioned Intex, they’re such a leading brand in the pool industry we had to review another offering from this company.

This model is a sand filter. Sand is a very cost efficient way of maintaining your pool since it’s an inexpensive material (compared to filter cartridges) and with proper backwashing doesn’t need to be replace more often than every five years. A filter cartridge, on the other hand, may need replacing every week.

Uses a digital timer to automatically turn the pump on and off
Uses Hydro aeration technology for improved circulation
Pressure gauge measure backwash

  1. For pools up to 120 square feet
  2. Filter dimensions: 11.8″ x 35.7″

Since Hayward has been in the pool game for so long (over 80 years, in fact) it’s no surprise they have more than one pool filter of such great quality we wanted to share it with you.

This filter is good for even bigger pools than the other one we reviewed. It’s dimensions are a little bigger so make sure you accommodate for its size, but with how powerful it is you won’t mind finding extra room under your deck for this model.

Pros

Has a single locking knob to fasten filter tank, no need for bolts
Maximum flow
Extra-large cartridge for extra strength filter
No backwashing necessary
Easy to install

Cons
Requires 2” connectors that may be hard to find
This great filter does come with a hefty price tag but we think it’s worth it if you have a bigger pool. Not to mention since you don’t need to backwash you’ll be saving countless dollars on the wasted backwash water.
