Help keep your bath clean and healthy with the purifying qualities of pure copper! 

Chemical free all natural 4" diameter copper water purification disk is 99.9% pure American made copper. It’s designed to sit up off the floor of the bath with 3 “feet” to ensure that the entire surface area of the disk is in contact with the bath water ensuring maximum benefit. The disk is made here in the USA with copper sourced from Revere Copper, Rome New York. Tarnished copper does not lose any of its beneficial qualities. Simply place in any bird bath for chemical free water purification.

The antimicrobial properties of copper surfaces are firmly established.                      Copper has been used since ancient times to disinfect and purify water. In modern times many scientific studies have proven that copper alloys possess excellent potential in controlling the spread of infectious diseases. In fact, after rigorous testing, the U.S. Environmental Protection Agency registered copper alloys as antimicrobial public health materials.

Importantly, research by the University of Southampton, UK, shows that copper can virtually eliminate the Influenza A virus within six hours of exposure. This is an especially important finding because a member of this virus family is the virulent Avian Flu strain.

In addition to eliminating bacteria and viruses, copper has also been proven to destroy mold and algae. Adding an Erva Anti-Microbial Bird Bath Disk to your bird baths will facilitate cleansing and contribute to the health and safety of your visiting birds by eliminating water-borne pathogens.

How It Works: The bactericidal activity of copper is mainly attributed to the release of ions, which are recognized by various microorganisms as an essential nutrient—and allowed to enter the cell. Once inside they affect the integrity of the membrane, generate intracellular oxidative stress and are genotoxic, meaning that the ions impede the cell from breathing, eating, digesting, or creating energy— resulting in the death of the microorganism. Antimicrobial copper continuously kills pathogens, even when tarnished. 
Using this Disk in Winter: This disk can be used in a heated bird bath as long as the heating element is fully enclosed. If there is any exposed coil DO NOT USE this copper bird bath purification disk. An example of a enclosed heated bath dish can be seen here.

Important Note: Copper will effectively help to control the development of harmful elements, but regular visitors to your bath will constantly bring new contaminants. The Copper Disk is NOT a substitute for proper, regular cleaning!

Copper Disc

Was skeptical this would work. I was so wrong. This summer I have had a horrible time with algae. Since starting to use this disc the problem is solved! The birds and I are happy 😊

Lotsa uses...

These are also great for cat fountains.

Works great

The copper disc has reduced the algae buildup 100% and is reduced the overall cloudiness by about 70% I don’t have to clean my birdbath quite as often. This is a great product from a company that I trust.

A good and useful product

I have these disks in several shallow birdbaths. They match the finish now that they have darkened. They extend the time between deep cleanings and inhibit mold. And so far no crows have stolen any.

Looks promising but this copper medallion has not been in service long enough to give an honest rating…

These discs are wonderful

These discs are wonderful and I really do think the birds appreciate and approve them!!!

Works so great I am buying more

I have been curious about trying one of these for a while. I needed to add a few dollars to my order to get free shipping, so I took a chance and added to my cart. I scrubbed my birdbath and added the disk not expecting too much. I am totally hooked, clearest the water has ever stayed for more than a week. I have ordered 3 more.

Beautiful disk

It’s winter here in NY so I haven’t been able to use in a bird bath. It’s bigger than i anticipated. So hope it works!

Thank God

My bird bath was such a mess until I got the little copper plate to put in the bird bath. Now it stays clean and the birds are enjoying it.

Honestly, didn’t think it was gonna work, but it did!

I have a birdbath with a little solar fountain that I typically have to clean at least once a week during the warmer months of the year. Once I added this copper disk, I haven’t cleaned it. It’s been two weeks and our temperature has been in the mid 70s. The water stays clear!

It’s working as advertised

Did not want to add any treatment to birdbath to quell
Algae growth as that is an endless battle. Summer time and hot humid conditions promote this growth and the Copper purifier is preventing any from accumulating.
Highly recommend.

Way cool

Love this little disc. Can’t wait to start using it in my birdbath.

Easy

Very easy to use, makes the bird bath easy to clean. If you have a large bird bath, I would suggest getting two.

Works as described!

My birdbath usually grows tons of algae and needs to be cleaned frequently but since placing the copper disk in it, it has remained clean and clear. I'm impressed!

Amazing!

This thing really works! I'm totally stunned. I've been fighting green gunk in my birdbath for years. It didn't matter if I washed it out every day with bleach, vinegar, special bird bath cleaners, or anything else. Fill with fresh water and the next day there is green scum all over the bottom of the bowl again. Winter was a bit less of a problem, but if the weather turned the least bit warm (and in recent years that happens quite frequently during the winter) the scum was back. I saw this advertised and hunted for them on many websites only to find they were always "Out of Stock." Found it here and thought I'd give it a try but not really expecting it to work and the green scum would win again. Well, it's been over a week now since I cleaned the bowl and placed this copper disk in. Fresh water added. I've been filling with fresh water every day and NO SCUM!!!!! I'm shocked, amazed, and VERY happy! Why didn't I find this 10 years ago? Don't hesitate to purchase this amazing copper disk. You won't regret losing the green scum that pervades the birdbaths of America!

Thank you for taking the time to review. We are so glad to hear that this product is working for you just as intended!

Amazing

I’ve tried a lot of things in my birdbaths and I can honestly say the disk works the best. I often had to change the water daily and sometimes more than once a day on really hot humid days but the disk really makes a difference. I recommend it highly.

Susan Cruit
It works!

I’ve had the copper disc for a week now. It has kept any algae from forming on all surfaces. The water is clear and fresh. It exceeded my expectations. It’s well worth having for the thirsty drinkers.

Why didn't I think of this sooner

I have on copper birdbath the rest are not. I never thought of adding something made of copper.
Sure beats cleaning a slimy birdbath.
On tiny birdbaths I just decided to throw some pennies in

I’m amazed- it works!!

Been using a couple of weeks-no algae!!

Erva copper disk

We have our birdbath out in the open so it always has sunshine! Over the years I would have to clean the algae out every few days. Since we got our Erva disk over two weeks ago I haven’t had to clean it at all because of algae and only once because of bird debris! Love it!

Does the disk have to be totally submerged?

Nature Niche

The entire surface area of the disk in contact with the bath water ensures maximum benefit. It is not recommended to have it partially submerged.

M
Mary

The disc doesn't seem to be working as well as it did at first. Should I clean the disc occasionally and how is the best way to clean it?

Nature Niche

The disk will slow down the growth in your bird bath, but you will still need to clean it at regular intervals. When cleaning your bird bath you can clean the disk as well. Here is a link to the owner's Mondays with Martha about how she sanitizes her birdbaths: https://nature-niche.com/blogs/mondays-with-martha/mondays-with-martha-60-part-2-how-to-clean-bird-feeders-baths

Will the copper disk work in a metal bird bath that is approximately 12-15”. Thank you!

Nature Niche

Yes, this disk is made for preventing algea growth in the water itself and works in many different kinds of birdbaths.
