When Should You Change your Aquasana Water Filter
When you should change the Aquasana filter varies among filtration system types and models. Aquasana has whole house, under the sink, countertop, and shower filtration systems.
Most of Aquasana’s filtration systems require filter replacement every six months, like the countertop filter, shower filter, and most of Aquasana’s under sink filters. However, the RO membrane and remineralize for the OptimH2O Reverse Osmosibest countertop water filtes + Claryum filter system are to be replaced yearly.
Aquasana’s whole house filtration systems include the pre-filter, main filter, and post-filter, so each part has different replacement schedules. Aquasana’s standard 10-inch pre-filter should be replaced every two months, while its 20-inch pre-filter for the OptimH20 model requires replacement every six months.
In regards to main filters, the 1,000,000-gallon RHINO main filter has the longest life span at 10 years, followed by the 600,000-gallon RHINO main filter at 6 years, and RHINO Well Water main filter at 5 years. The OptimH2O main filter, however, requires replacement every year.
Aquasana’s post-filters require replacement every 6 to 12 months. It also depends on your water’s sediment levels.
Moreover, add-ons you may have included in your whole house system, like the UV light and water conditioner, would also have their respective schedules for maintenance. For the UV light, it’s every 12 months. For the water conditioner, it’s every 6 years.
What Does the Red Light in your Aquasana Filtration System Mean
Some Aquasana filtration systems come with an alarm system, which includes a beep sound and a light indicator. When it’s time to change your filter, the Aquasana filter beeping would sound. And the Aquasana red light would appear on the light indicator.
By the time you change your filter, a change of alarm battery would also be required. It’s important also to change the alarm battery, as this helps in filter maintenance. An alarm battery comes with your purchased filter, so there’s no excuse for you not to change it.
Conclusion
Aquasana water filtration systems are favorably designed for the ease of filter replacement for Aquasana users. Anybody can easily replace Aquasana filters just by following the instructions.
There is also the added convenience of the alarm system in some models and the assistance of Aquasana’s customer service in case Aquasana users encounter troubles.
