Should I Run My Pool Filter All the Time?

As a pool owner, you are responsible for keeping your pool water sparkling clean and healthy for swimmers. One of the key components of maintaining a clean pool is running your pool filter. But, is it necessary to run it all the time? Let's take a closer look.

The Importance of Pool Filters

A pool filter is responsible for capturing and removing dirt, debris, and other contaminants from your pool water. Without a filter, your pool water would quickly become cloudy, algae could grow, and the water could become unsafe for swimming. The filter also helps to circulate the water, ensuring that chemicals are distributed evenly, preventing stagnation of water and reducing potential breeding of mosquitoes, mold, and bacteria. Ultimately, a pool filter is essential in keeping your pool clean and safe.

The Benefits of Running Your Pool Filter All the Time

Running your pool filter constantly brings a number of benefits to your pool. Here are some of the reasons why you should consider running your pool filter for extended periods:

1. Cleaner and Clearer Water

When your pool filter runs continuously, the water is continuously filtered, resulting in clearer and cleaner water. The filter can capture contaminants more efficiently if it is given enough time to do so.

2. Lower Levels of Chemicals

Running your pool filter regularly will help to distribute chemicals evenly throughout the water. This reduces the amount of chemical needed in the long term as there won't be certain areas with less chemicals, and other areas with too many chemicals.

3. Improved Efficiency

Running your pool filter for an extended period of time can help to improve its efficiency by allowing it to run at a lower flow rate. This is because when a filter runs at a lower speed, it can trap smaller particles that would otherwise have passed through the filter.

4. Saves Money

While running your pool filter constantly may result in higher utility bills, it can still save you money in the long run. This is because running your filter for longer periods regularly reduces the amount of chemicals needed in the water, and it can extend the life of the pool equipment. Clean water invariably means less wear and tear on filters, pumps, and other equipment.

5. Prevents Algae Growth

Algae growth can be a real problem for pool owners, and the best way to prevent this is to keep the water moving, and regularly filtered. A filter that runs constantly will ensure that water is being circulated throughout the pool and that algae is less likely to form.

The Drawbacks of Running Your Pool Filter All the Time

Despite the benefits, there are some potential drawbacks to running your pool filter constantly:

1. Increased Energy Costs

Running your pool filter for extended periods will naturally lead to higher energy bills, and this can be a concern for some pool owners.

2. Filter Wear

Every piece of machinery in your pool has a limit, and pool filters are no exception. Constant use of the filter could lead to wear and tear, reducing the lifespan of the filter.

3. Maintenance

Keeping your pool filter running all the time means would need more maintenance. Ensuring the filter systems aren't backed up or clogged and regular replacement of the filter media to ensure effective filtration.

4. Noise

Some filter systems can be noisy when they run, and if yours is located close to your house or your neighbour’s, running your filter all day and night could be a nuisance.


In conclusion, running your pool filter constantly does have its benefits, but it's not always necessary. Ultimately, it is up to you as the pool owner to determine the appropriate running time based on a number of factors including cost, energy consumption, and the level of maintenance you are willing to commit to. You can save money and maximize results by finding an appropriate balance, and a schedule that suits your needs.
