APEC Water ULTIMATE RO-PH90 Reverse Osmosis System


The RO-PH90 is the best model in APEC’s ultimate series when it comes to providing great tasting water. It’s much similar to the RO-90 but features an extra stage which comprises of an alkaline filter that enhances the taste of your source water.

If you prefer a more natural and better-tasting water with some healthy minerals in it, then the RO-PH90 might just be the right choice.

Filtration Process

The system uses a 6-stage filtration process to enhance the water purity and its pH level.

The 1st stage is the effective 5-micron polypropylene sediment which traps all the dirt, dust, rust, silt, sand and other large particles and contaminants in the water.

The 2nd and 3rd stages are occupied coconut shell carbon block filters. These are premium-grade filters that will get rid of any unpleasant taste, odor, colors and cloudiness.

More importantly, they will remove chlorine, chloramines, VOCs and many other chemicals present in the water. 

All the remaining contaminants are completely removed at stage four. The 0.0001-micron FILMTEC TFC RO membrane captures up to 99% of the total dissolved solids (TDS) and contaminants from heavy metals to chemicals to microorganisms such as bacteria and viruses.

The 5th stage is occupied by another coconut shell carbon filter which absorbs any unpleasant taste that may arise from the RO holding tank.

6th Stage – Alkaline Filter

The RO-PH90 features an additional stage which consists of a calcium mineral cartridge that serves as an alkaline filter. It effectively raises the pH of the RO water naturally by adding calcium carbonate which neutralizes the slight acidic RO water.

It increases the pH level to about 8 to 9 which makes the water more alkaline with a much better taste than the plain RO water.

Filtration Capacity

Like the RO-90, this unit comes with a high capacity membrane which is capable of delivering 90 gallons of water per day. That capacity will satisfy the water needs of any family or household whether medium or large.

The wastewater to the pure water ratio is 3:1. It’s no different from the other APEC’s models. It will waste some water but a moderate amount not to hike your water bills.

Installation and Maintenance

The installation of the RO-PH90 is pretty straightforward too. The instruction manual is clear and easy to understand plus there is nothing complicated to set it up. If you have basic DIY skills, it can take you about an hour.

APEC’s RO systems, parts, and filters are always built to last and the RO-PH90 is no different. The filters are of high quality and long-lasting.

The prefilters and the alkaline filter require changing only once a year while the RO membrane and the post-carbon filter can serve you for about 3 to 5 years.

In short, with regards to performance and overall functionality, the APEC RO-PH90 is up to the task. The addition of the alkaline filter is a big plus especially for those that prefer great-tasting alkaline water.

FAQs

Can I use this RO system like a whole house system?

No, the capacity and performance is not enough for whole-house use.

Should I clean the Sediment and carbon pre-filter?

No, it’s not recommended to clean the pre-filters but you should replace them regularly.

Will this RO system work with lake water?

Yes, just make sure the water pressure at the inlet is about 50-60 PSI for the best performance.

Why does this product have a prop 65 warning?

The proposition 65 in the state of California has very stringent guidelines. This proposition mandates that all the products, packaging, and places that may contain certain chemicals, even in minuscule amounts, must display this label notice. For this reason, the majority of products that are sold in the state of California are required to display this warning.
