Simple question, would you rather swim in a pool with clean water, or one with dirt, debris and other contaminants? Well, your answer is obviously the clean pool. The difference between the two is brought about by the level of maintenance, and majorly, by the effectiveness of the pool filter at purifying the water. In fact, they say that filtration is the key to keeping the pool clear. So, what is a pool filter? It's a filtration system, which is installed into a pool construction to capture any debris that would otherwise accumulate in the water. This is achieved as a continuous cycle with the pool water going back and forth through the filter and back into the pool in a bid to have all the pool water clean, clear and safe.

Types of Pool Filters

There are 3 main types of pool filters, each of them intended for different needs of the user or owner of the pool. These include the sand filter, cartridge filter and Diatomaceous Earth (DE) filter. The sand filter is obviously filled with sand that captures any dirt from the water. The cartridge filter uses a pleated filter material for this purpose while the DE filter makes use of DE powder-coated grids for this purpose. Each of these has its pros and cons. For any pool owner that wants to replace their old pool filter or purchase one for their new pool, choosing one is quite a complicated procedure for most people. However, after reading this buyer’s guide, this will no longer be the case. You will for once have it easy making the ultimate decision on exactly which pool filter to invest in.

How to Choose the Right Pool Filter

  1. Consider the Size of the Pool.

    Since there are myriad models of pool filters in the market, each with its own unique power, it is important to calculate the size of the pool so you can know the exact model that will accommodate that amount of water. You must also know the maximum volume of water that can be accommodated by the pool at a go. It is best to convert the volume of the water in gallons so that it becomes easier to pick the filter with the correct gallons per minute/hour speed. This way, you can estimate the period it takes for the all the water in your pool to be filtered.

  2. Check the Flow Rate of the Water.

    The speed with which water flows through the filter is the biggest determinant of the pool’s turnover rate. Given that most states have different laws regarding the pool’s turnover rate, it is important that you use the flow rate and volume of the pool to calculate turnover rate, which is the rate at which the filter can get all the water in the pool filtered. In fact, most states advise that the best pool filtration system should have a turnover rate of at most 12 hours. This means that all the water in the pool should be filtered within 12 hours per round, which ensures supreme cleanliness.

  3. Check out the Different Types Available.

    As mentioned above, the most common types of pool filters include sand, GE and cartridge filters. Depending on your budget and expectations, one or two of these filter types may work for you idyllically. If you want secure filtration of your pool water, then sand filters are your perfect choice. If low maintenance is what you seek, then the cartridge filters will work for you, and if you want the cleanest water, then go for the DE filter. Apparently, even if you own a sand or cartridge filter, you ca still get the cleanest water by adding some DE to their sand or cartridge, thus making it easier to filter even the smallest particles. Alternatively, adding Flocculants to the pool water will create bigger particles from the smaller particles for better visibility and easier capture.

  4. Deliberate on Ease of Maintenance.

    The best machines in the world are those that are so easy to maintain. Find a pool filter that is easy to clean, install, use, repair and replace its parts. This ensures that whenever you have a faulty filtration system, you don’t need to hire an expert if you know how to go about it. Instead, you’ll pick up your tools and conduct the maintenance procedures by yourself. Also, make sure that the brand you invest in has very accessible spares and installers, which reduces the cost of outsourcing from far places.

  5. Confirm its Durability.

    Every buyer usually wants an appliance that offers durability. Since most pools are built with the aim of lasting up to several decades, it is important that the pool filter follow this pattern of durability. The materials used to build it should be strong and resistant to rust and corrosion from the chemicals in the water. This information is best obtained from the manufacturer’s website, but you can also get it from the seller’s website or user forums where buyers and users post reviews, ratings, testimonials and complaints about different products.

  6. Research and Seek Recommendations.

    If you are sure that you want to replace your old pool filter with a similar model, then you don’t need to go through this step. However, if you are planning to invest in a different brand or model, it helps to ask friends, relatives or neighbors about their experience with the different models they have owned or used before. You may also check the buyer and user reviews from the manufacturer’s or seller’s website, as well as user or buyer forums.

  7. Always Go Bigger.

    Once you have identified the volume of your pool and the water flow rate, you can easily determine the turnover rate you desire, which is useful in knowing the size of the filter to purchase. You must invest in a pool filter that offers sufficient space for faster filtration of the water. In fact, it is always advisable to get a pool filter that is bigger than you need, but this doesn’t mean that you go for the biggest commercial pool filtration system when all you need is a small kiddie pool filter.

  8. Buy Within Your Budget.

    Regardless of where you live, budget is the constant factor that rules everything. With a lot of money, you are guaranteed the best quality, but with little money, then getting a high quality filter is a gamble. You have to buy a pool filter that you can easily pay for maintenance or replacement without breaking a sweat. Purchasing a pool within your budget will surely give you some peace of mind, knowing that you can afford to keep your pool up and running without spending a fortune.

Why Invest in a Pool Filter?

For most people, a pool’s filtration system and pump are considered the heart of in-ground or above ground pool. For this reason, they should be at the utmost quality you can afford and in perfect working condition. Apart from keeping your water free from dirt, debris and contaminants, a good pool filter will ensure that the water is safe and healthy for use, and that the pump and filtration system keeps working flawlessly without issues such as clogging and breakage. Depending on your degree of pool usage, you need to keep a regular pool filtration regime according to the set standards of the area you live in.
