On the other hand, pool equipment and pipework not so much. 

The very best thing you, or I, could do to conceal any unsightly pool hardware is to invest in a simple fix like a filter box. 

Ranging from run of the mill homemade wooden boxes to specially designed, sound-reducing crafted cases. 

Whichever one you do eventually choose, you’ll need to know a few key facts about planter boxes and your pool fence. 

But rest assured spending 5 minutes reading this article and another 5 minutes carrying out the necessary safety checks, you could prevent a child from accidentally drowning in your pool. 

Let’s answer the most important question first: 

What is a filter box? 

A filter box, as the name suggests, is a box that covers your filter. 

In essence it’s just housing for your pool pump and equipment, which protects your gear from the elements and keeps it out of site, all while allowing easy access. 

It can come in a number of shapes and sizes; ranging from the simple wooden box casing to elegantly crafted and specially engineered designs. 

If you’re in need of a new pool filter box, but you don’t want to spend an arm and a leg, why not try and build your own pool filter box? 

It’s a fun weekend DIY project, that lets you add whatever personal touches and finishes you want. 

Now you know what a filter box is, and you’ve got a handy guide to building your own pool filter box, let’s talk about the important safety issues you need to be aware of.  

Pool Filter Boxes & Non-Climbable Zones (NCZ) 

Making sure your pool fence’s non-climbable zone (NCZ) is safe and secure is a vital part to ensuring your pool area is safe for your family and neighbourhood. 

Ensuring your pool filter box is outside of your NCZ is a crucial step to making sure you have maintained an area around the pool area free of climbable objects a young child could use to access your pool. 

It certainly isn’t just to make sure your pool meets legislated standards, but to ensure your pool is safe for everyone around it. 

To give you a re-cap on what your NCZ is: 

The non-climbable zone is an area that pool owners must maintain as a preventative measure against children climbing over fencing into the pool area.  

The NCZ is measured as an arc shape from the top of the pool fence arching towards the ground.  

It also includes the space extending 30 cm inside the pool area, where you should also keep it free from any potential footholds or handholds.  

Any horizontal climbable bars on your pool fence must also be spaced at least 90 cm apart.  

If you’re still unsure, simply snap us a photo of your pool to our mobile number or e-mail address and we can take a quick look for you.  


We’ve covered what a filter box is, as well as some safety issues you’ll need to be aware of with regards to your non-climbable zone. 

Moving on: 

Now the next step for you is to give your pool filter box a super quick once over to ensure it’s safe and compliant with NSW pool safety standards. 

Improving your understanding of a pool filter box and understanding the important safety factors you need to be aware of, could potentially save a life… 

… and it only takes less than 5 minutes of your time! 

The best thing about it? 

You’re not just making sure you’re doing the right thing by the law, but you’re also doing the right thing by your family, friends and community.
