Info: 4 Filter, 5 Stage Water Purification System
Shipping included in Canada! The OPUS CottagePure is a five-stage drinking water purification system capable of destroying over 99.95% of bacteria and viruses. Designed for lake water, well water, or other water supplies that have not been through a water treatment plant, it purifies and sterilizes without using harmful chemicals, to produce great tasting water free of micro-organisms and contaminants. And unlike reverse osmosis and distillation, it retains dissolved minerals (including calcium and magnesium) in solution, to create a balanced, great tasting mineral water with no effect on pH (alkalinity).
This system features four filtering stages in three vertical compartments of a housing unit, along with an ultraviolet light chamber on top for disinfection -- a safe, natural process that adds no chemicals and does not adversely affect the taste or odor of your water -- to remove heavy metals, chlorine, dissolved and particulate lead, mercury, trihalomethanes, and VOCs, with a 99.95% reduction of cryptosporidium, giardia, entamoeba, E. coli and toxoplasma cysts... almost instantly! CottagePure eliminates the need to boil or bring in all your drinking and cooking water to protect you and your family or guests from water-borne illnesses from untreated water.
CottagePure uses four advanced filtration components to provide five stages of water purification in a standard three chamber vertical 10" housing design. The system is capable of destroying over 99.95% of bacteria and viruses, purifying and sterilizing water without the use of harmful chemicals. This system produces great tasting, contaminant and microorganism free drinking water. (This system does not remove fluoride, however.)
The germicidal ultraviolet sterilization filter is rated at 1 gallon per minute. To ensure optimum sterilization, the system restricts water flow to 2.3 litres per minute to achieve the NSF/ANSI standard of 40mj/cm², ensuring effective disinfection of all pathogenic microorganisms.
The system is designed to be installed under the sink or in an area that provides convenient access for filter changes. The system includes a beautiful brushed nickel ceramic disk designer faucet with a John Guest quick connect screwed on the end, to make it easy to attach the supplied tubing. Two 5 foot lengths of BPA free 1/4" LLDPE tubing is included to connect your cold water source to the system, and the system to the faucet. Your installer will need to supply components to connect the system to your cold water supply. The system includes four advanced filters with five filter technologies, housed in three 10" under-the-sink filter containers, with a horizontally mounted UV-C sterilization filter. AC power is required for the UV-C sterilization filter; however, only six watts of power is required.

Customer Review: OPUS Cottage Water Treatment System
We purchased the OPUS Cottage Water Treatment System from Aviva two years ago and are very satisfied with it. We live on a small lake in North Western Ontario, and by August the water is quite green, with a distinct algae taste. Using the OPUS system we get clear water with a very agreeable taste. Previously we were buying distilled water for around $500-$600 dollars a year. This system easily paid for itself in the first year. It came with extra filters, so we just had to replace the UV light after the first year. Annual maintenance to replace filters and light is about $130.
I agree with the suggestion on the Aviva website that you have this unit installed by a professional. My plumber didn’t like the connection valve that came with the system, and installed a t-junction instead. We take the water from the OPUS system and put it into a Greenway water system (available from Canadian Tire for $40) that sits on top of the water cooler we purchased from World of Water. This gives us about 7 litres of cold water on tap all the time. Refilling is a snap.
I heartily recommend this system, and imagine that any of the large OPUS systems would also function well. (We went with this simple system because it only has filtration and purification without fluoride.) I checked out other UV systems before I purchased. This system is competitively priced.

The individual components included in the five stage design include:
- Stage 1: 30 micron dirt/rust/sediment filter (3 extra filters are included).
- Stage 2: 1 micron dirt/rust/sediment filter (3 extra filters are included).
- Stage 3 & 4: Advanced 2 stage flow restricted microfiltration filter featuring Spun Fiber, for sediment removal to 0.5 micron; and Powdered Carbon, for removal of metals, lead, chlorine, VOCs, MTBE, THMs, pesticides and a wide range of contaminants (1 extra filter is included).
- Stage 5: 1 GPM flow rate UV-C sterilization filter with AC transformer adapter.
Stage 1 – 30 Micron Spun Polypropylene: Installed in the left filter container, the spun polypropylene microfiber dirt, rust and sediment filter removes particles 30 microns or larger (the majority of particles in lake and untreated water), extending the life of the 1 micron filter in Stage 2. This filter should be changed when water pressure significantly drops.
Stage 2 – 1 Micron Pleated Sediment: The filter installed in the middle container is a one micron pleated filter, to trap particles 1 microns or larger. Particulate matter smaller than 1 micron will be captured by the third (.5 micron) filter. If water pressure is still low after replacing the 30 micron filter, this filter should be replaced.
Stage 3 & 4 – .5 Micron Carbon Filter: The third filter, installed in the right container, is a 2-in-1 (2 stages in one filter component) .5 micron powdered carbon filter designed to remove a wide range of contaminants. A unique feature of this filter is that it is flow-restricted to 2.3 litres per minute, to ensure adequate sterilization by the final UV sterilization filter. If water pressure continues to be low after replacing the 30 micron and 1 micron filters, this filter should be replaced.
An important feature of this filter is to ensure there is no turbidity (cloudiness) of the water that passes through the germicidal ultraviolet (UVC) filter. For effective sterilization, the water that passes through the UV-C filter must be crystal clear. This filter, rated at .5 micron, ensures that the water entering the final UV-C filter will be properly sterilized. It is critical that the flow restricting component, which looks like a small round piece with a hole in the centre, is facing upwards when this filter is installed.
The two stages of this 2-in-1 filter include:
– Stage 3: Spun fiber for sediment removal down to .5 microns (microfiltration).
– Stage 4: Flow restricted powdered carbon filter that adsorbs (removes) heavy metals, chlorine, dissolved and particulate lead, mercury, trihalomethanes, VOCs, and reduces cryptosporidium, giardia, entamoeba and toxoplasma cysts by 99.95%, ensuring the water is crystal clear with no turbidity for effective UV sterilization.
Stage 5 – Germicidal UV-C Sterilization Filter: Ultraviolet light effectively kills bacteria, viruses, mold, algae, yeast, cysts (including giardia and cryptosporidium), some volatile organic compounds and other biological contaminants. Replace after 12 months of use.
Unlike chlorine or chloramines (toxic chemicals used to kill micro-organisms), UV-C sterilization systems do not add any potentially poisonous or harmful chemicals into your drinking water or adversely affect the taste or smell. Unplug from power when not in use for more than a week to maximize the life of the UV-C lamp. The UV-C filter (bulb) uses six watts of power.
Extras, Replacement Schedule, and Installation Requirements
CottagePure comes complete with 7 extra filters (10 in total), two 5 foot lengths of 1/4" BPA-free linear low density polyethylene tubing (LLDPE), a brushed nickel ceramic disk faucet with a quick connect attached for easy connection to the water output tubing, and a filter wrench. How long these filters will last will vary depending on the particulate and contaminant levels in the source water; however, the system should provide one summer season or more of use before additional filters are required. An annual filter kit includes four 30 micron filters, four 1 micron filters, two 0.5 micron 2 stage filters, and a replacement UV-C lamp.
As leaks and filter damage can result from improper installation, all OPUS filtration products should be installed by either a licensed professional plumber, or by someone experienced in water filtration installations. CottagePure requires AC power for the UV-C sterilization filter; however, the bulb only consumes 6 watts of electricity, so many cottages using solar power will be able to power the unit. Dahl valves and SharkBite TEE components are recommended for the highest quality installations. A saddle valve, for 1/2" copper pipe, is available for $8.50.
Replacement filters can be bought as individual replacement water filters or as part of an Annual Water Filter Replacement Kit. For detailed information on how to install them, please download the Cottage Pure water system Installation Guide.[PDF]
OPUS recommends all water/plumbing products be installed by professionals. Be sure to flush the filters in the proper order before hooking up and using the whole system, as indicated in the Installation Guide. The CottagePure also requires connection to an AC electrical outlet, to power the germicidal UV-C sterilization component.
