We recommend hand washing the lid, reservoir, and carafe every 3-4 weeks with hot soapy water (DO NOT CLEAN THE FILTER). Whenever possible, keep the Aozora Filter Pitcher out of direct sunlight to prevent bacterial growth.

Depending on the hardness of your water, pitcher filters should be changed every 80 gallons of water or about every 4 months, whichever comes first.

The water filtration of your Aozora water filter is slower than most competitors because our the 4-stage filtration which remove a much larger range of contaminants. 

However, if you think that your water filter is filtering too slowly, you may need to re-flush your filter cartridge again by following the flushing instructions included in the user manual.

If this issue persist, please contact Aozora Customer Service at support@iaozora.com and we will help you resolve.

The Aozora Water Filter consist of 4 stages that removes organic and inorganic contaminants in your tap water.

2. Activated Carbon Granules:
Effectively reduces chlorine, odors, impurities and other chemicals. Particularly good on organics and for improved taste.

The Aozora filter removes up to 99.99% of tap water contaminants. This includes fluoride, chlorine, pesticides, trace pharmaceuticals and other known menaces of municipal tap water. The filter’s proprietary technology meets and exceeds NSF Standards 42 and 53 for contaminant reduction. This means that it is thoroughly tested to make water odorless and fresh-tasting, as well as remove a variety of health-related contaminants. Better still, it does all this without removing health-essential minerals from the water.

Many filters like Zerowater filters have been marketing themselves based on their ability to remove TDS. However, TDS is not a measure of water contaminants. Much of what constitutes TDS is actually healthy minerals like calcium and magnesium, which Aozora is designed NOT TO REMOVE.

Note: even if your water has a TDS reading of zero, it means that your water does not contain healthy minerals anymore.

According to the NSF Consumer Fact Sheet on TDS, which is linked below, “A TDS meter does not directly measure heavy metal contaminants such as lead or arsenic in the water.  A TDS reading is not an indication as to whether a water filter is working properly to reduce these contaminants.”

The Aozora filters are designed to keep healthy trace minerals in your water like calcium and magnesium while removing toxic contaminants.

No, Aozora water filters are not designed to filter salt water. We do not recommend using any of our products with anything but fresh water.
