Review on 💧 Aquaboon Filters Premier 5 Stage Replacement: High-Performance Water Filtration System by Jonathan Yang

I have changed the filters many times in this ten year old four stage system. I used to buy replacement filters from Costco but they are no longer available. These filters were the least expensive alternative. I bought them over a month before I changed them and the return window closed. Coarse filters and activated carbon filters are fine. Gaskets on activated carbon filters could fit a little better so they don't fall off as easily. The final filter is defective and should never have passed a quality check; One of the ends has no thread at all and will not fit the thread adapter - the other end has a standard 1/4" thread. After 30 days there are no returns/replacements for goods with a defect. Purenex P-7PK RO -Filter Premier 1 year, 5 steps
