Buying Guide
A high capacity filter catches more dirt. It lasts longer too.
I tried one on my pump. It cleaned water fast.
-
Size: Choose a filter that fits your space. Measure the opening first. Bigger size holds more dirt.
-
Material: Look for strong plastic or metal. These last longer. They resist rust.
-
Flow Rate: Pick a filter that lets water flow well. Too slow blocks pressure. Too fast lets dirt slip.
-
Micron Rating: Small numbers catch tiny particles. A rating of 5 µm is good. Check the rating label.
-
Maintenance: Easy clean filters save time. Some can be rinsed. Others need replacement parts.
-
Compatibility: Match the filter to your system. Check pipe size and thread type. Wrong fit can leak.
-
Price: Set a budget you can afford. Higher price often means longer life. Find the best value.
-
Brand Reputation: Trust brands with good reviews. Look for warranty info. A known brand means less risk.
