7Plus RO Filter Maintenance Schedule: When to Change Each Cartridge and What It Costs

The 7Plus RO filter does not need maintenance every month, but it does have three dates you should not forget over roughly a year and a half. In this guide we lay them out on a simple timeline: what to change at each date, what each batch costs and how to remember the date.

We are talking here about the 7-stage RO water filter with a 24 V pressure pump.

Key takeaways

• After 12 months: replace the cartridges of all seven stages with a pack at 210 dirhams
• The membrane is changed between 12 and 18 months depending on water salinity, at 220 dirhams
• The annual pack is available at 560 dirhams

The schedule at a glance

• Month 6: the first three cartridges, at 130 dirhams.
• Month 12: the cartridges of all seven stages, at 210 dirhams.
• From month 12 to 18: the membrane, at 220 dirhams depending on water salinity.
• Annual pack: at 560 dirhams.

The first six months: no changes

After installation you do not need to change any cartridge during the first six months. Just note the installation date and pay attention to the water flow and taste so you know your device’s starting condition.

The sixth month: the first three cartridges

After six months, the first three cartridges of the device are changed, the ones that hold back sediment and limit chlorine and odors before the water reaches the membrane. This batch costs 130 dirhams. Delaying it strains the remaining stages and gradually brings back the old taste.

The twelfth month: the cartridges of all seven stages

After twelve months, the cartridges of all seven stages are changed with a pack at 210 dirhams. This is the biggest date in the device’s cycle, so make sure you do not miss it.

The membrane: between 12 and 18 months

The membrane is the heart of reverse osmosis and costs 220 dirhams. Its lifespan ranges from 12 to 18 months depending on water salinity: the saltier the water, the closer its date gets to 12 months. If the salty taste returns before the date, read the signs that cartridges need changing.

How to remember the dates?

• Write the installation date on a sticker near the device.
• Set a reminder on your phone at month 6, month 12 and month 15.
• Message us on WhatsApp at the time of installation if you want to ask about the next date.

Before you open the device

We do not offer an installation service in the store, and we recommend having a plumber do the installation or the cartridge changes if you are not comfortable doing it. Whoever does it, shut off the water supply to the device and disconnect the pump’s power before opening any stage, then follow the manufacturer’s instructions supplied with it. After reassembly, run the device for a few minutes and check that there are no leaks.

How much does maintenance cost?

Maintenance is paid in batches: 130 dirhams at the sixth month, 210 dirhams at the twelfth month and 220 dirhams for the membrane when its date comes. Those who prefer to buy everything at once can choose the annual pack at 560 dirhams.

What if you go past the date?

The cartridges’ efficiency gradually declines, so the flow drops and the old taste returns, and the salty taste may come back if the membrane is late. The longer you wait, the more you strain the remaining stages. It is best to keep to the schedule.

How to order the cartridges

You will find the cartridges and packs on the home water filter with pressure pump page. Delivery is free to all cities in Morocco and payment is on delivery. If you are not sure which batch suits your device, message us on WhatsApp.

Conclusion

Three dates govern the maintenance of the 7Plus RO filter: the sixth month for the first three cartridges, the twelfth month for the cartridges of all seven stages, and between 12 and 18 months for the membrane. Note the installation date, set a reminder, and your filter will keep working as it did on day one.
