1 Micron Microtec Sediment Replacement Filter Information

Keep your aquarium water clean and clear with the 1 Micron Microtec Sediment Replacement Filter Pet Store. This product will help your reverse osmosis unit to efficiently work. This replacement filter uses polypropylene fabrics that are thinly spun together to create a filter cartridge with super fine density.

It filters out different forms of impurities in the water such as debris, food remains, wastes, and other undissolved particles. You will have a cleaner, clearer, and healthier water environment. Your fishes, corals, and other creatures will grow and develop better. Using this filter media in your freshwater or marine environment will make it safe and free from different viral, fungal, and bacterial infections. Even beginners can use this product because installation is very easy. It fits easily inside any RO unit.

This product will not change the mineral balance of the water when used within the required temperature of the tank. This is very convenient to use because it is long-lasting. You will not need to replace it often because it remains efficient for up to one year. You can simply dispose used cartridge by simply throwing it straight in the garbage can. Make your water environment clean, healthy, and odor-free by using an affordable yet efficient filter cartridge. Give it a try today.

Comments: Does a good job of filtering out sediment. Might do a better job for me, but it doesn't really fit the Spectrapure MPDI-25 unit. The center bore of the filter isn't wide enough to fit around the outer ring at the top and bottom of the housing ... I have to press the filter down so the ring is forced into the fibers of the filter, which may affect the filtering, and also causes the filter to be tilted within the housing (it's basically too high).

Comments: i have been using these sediment filters for a while now. Although this isn't the "best" you can get, these perform more than adequately, and the price is a huge plus. With my 4-stage RO/DI setup, and taking into account the cost of carbon filters (I use .5 micron), I have found these allow for more gallons/$, when compared to the more expensive models of sediment filters you can buy. The finer sediment filters get clogged quickly are are pricey to replace often, whereas these are inexpensive enough to replace on a regular basis.
