Review: useless - useless
Review: I bought this item with my own money, with no remuneration from anyone of any type. No coupons, no free item for a review. This is what I think of the product in my own words after having used it. I installed this filter in my Alexa as soon as it arrived. It is very easy to install. It filters fairly quickly. I have had no problems with it whatsoever. My water tastes great, so I know filtering is going on. I don't know about anyone else but I cannot continue to purchase Alexa brand filters because they have increased so much in price. So for now this will do. As long as it gets out some junk it's still better than straight tap water.

## Features

- 💎 PORE SIZE of 0.2 to 0.5 micron (human hair is 40 to 300 microns) In other words, the stated pore size of filter isn’t literally the size of the pores. It’s a rating of what can’t pass through them. Obviously, when sterilizing water, the object is to physically remove particles suspended in the water. The smaller pore size a smaller amount of contaminates will pass them
- 💎 SILVER IMPREGNATED A low-cost technology to treat water at the household level is the ceramic silver-impregnated filter. The ceramic filter is a promising treatment system to supply safe drinking water especially to people living in rural areas
- 💎 REMOVES: impurities and volatile organic chemicals. This Filter Removes up to of following contaminates: 99% of Arsenic 5, Taste, Odor & particles larger than 0.3 micron; 98% of Aluminum, Lead & particles larger than 0.2 micron; 96% of Iron. TRAPS: dirt, sediment, contaminants, debris
- 💎 LIFE OF FILTER is 1000 gallons or 1 year whichever comes first. To achieve better results recommended maintenance is at least once a month, or as often as necessary, depending on the quality of water. Over time, the trapped dirt and contaminants will begin to buildup, forming a layer of gunk on the surface of the ceramic filter. Scrubbing the surface of the ceramic dome with a scouring pad or soft brush under cool running water will unclog the pores on ceramic and expose a new layer for use

Recibí el producto con un defecto de fábrica. La parte de abajo está despegada, lo que afecta su funcionamiento y hace que no filtre el agua correctamente. Esperaba mejor calidad en el filtro.
