Water Travels Through 13 Stages of Filtration:

STAGE 1 - Water travels through a 5 micron solid carbon cartridge for removing volatile organic carbon compounds (VOC's), insecticides, pesticides and industrial solvents and traps particles larger than 5 micron including sediment, silt, sand and dirt. It also helps to extend the life of the system.

STAGE 2 - Water passes through a 0.020 micron Ultrafiltration (UF) membrane. Ultrafiltration (UF) is an important purification technology used for the production of high-purity water. UF is effective for the removal of colloids, proteins, bacteria, viruses, parasites, protozoa and pyrogens (e.g., gram-negative bacterial endotoxins), other organic molecules larger than 0.020 micron, and most other water contaminants known today. 

STAGE 3 - Water flows through pre one - micron filter pads (1 micron equals 1/25,000th of an inch), which removes suspended particles such as silt, sediment, cyst (Giardia, Cryptosporidium), sand, rust, dirt, and other undissolved matter.

STAGE 4 - Water passes through granulated activated carbon (GAC). GAC is universally recognized and widely used as an effective adsorbent for a wide variety of organic contaminants, such as chlorine, chemicals linked to cancer (THM's, benzene) pesticides, herbicides, insecticides, volatile organic compounds (VOC's), PCB's, MTBE's and hundreds of other chemical contaminants that may be present in water, bad taste, and odors from your drinking water. .

STAGE 5 - Water flows through the ion exchange resin, reducing heavy metals such as lead, copper, aluminum, and water hardness.

STAGE 6 & 7 - Water flows through 2 beds of Eagle Redox Alloy®(Oxidation/reduction process) media made of a special high-purity alloy blend of two dissimilar metals - copper and zinc. Representing a new and unique way of water processing medium which by its natural process of electrochemical oxidation/reduction and adsorption action reduces and/or removes many unwanted contaminants from water. It is a major advancement in water treatment technology that works on the electrochemical and spontaneous-oxidation-reduction (Eagle Redox Alloy®) principles. Chlorine is instantaneously and almost inexhaustibly oxidized.

Iron and hydrogen sulfide are oxidized into insoluble matter and attach to the surface of the media. Heavy metals such as lead, mercury, copper, nickel, chromium, cadmium, aluminum, and other dissolved metals are removed from the water by the natural process of electrochemical process. They are attracted to the surface of the media, much like a magnet. The media inhibits bacterial growth throughout the entire unit. 

STAGE 8 - Water flows through another one-micron filtration pad for further reduction of undesirable particles. The end result is a great reduction or elimination of a wide variety of contaminants.

STAGE 9 - Water passes through a CRYSTAL QUEST® reverse osmosis membrane, which removes and filters particles as small as 1/10,000 of a micron as most inorganic chemicals (such as salts, metals, minerals) most microorganisms including cryptosporidium and giardia, and most inorganic contaminants. 

STAGE 10 & 12 - Water flows through another one-micron filter pads (1 micron equals 1/25,000th of an inch), which removes suspended particles such as silt, sediment, cyst (Giardia, Cryptosporidium), sand, rust, dirt, and other undissolved matter.

STAGE 11 - Water passes through granulated activated carbon (GAC).

STAGE 13 - Water travels through a 0.20 micron Ultrafiltration (UF) membrane. Ultrafiltration. UF is effective for the removal of colloids, proteins, bacteria, viruses, parasites, protozoa and pyrogens (e.g., gram-negative bacterial endotoxins), other organic molecules larger than 0.20 micron, and most other water contaminants known today.

Features

  1. 50 Gallons Per Day
  2. Granulated Activated Coconut Shell Carbon (GAC) Filter Cartridge, post membrane cartridge, to remove volatile organic carbon compounds (VOC’s), insecticides, pesticides and industrial solvents.
  3. Water Pump
  4. Ultrafiltration

Comes with a complete installation kit that includes a European lead-free long-reach designer faucet, CRYSTAL QUEST® 3.2 gallons stainless steel pressurized holding tank with a polypropylene inner liner and a 2.0 gallon capacity, all interconnecting color-coded tubing, filter cartridges, Ultrafiltration membrane, RO membrane, wrenches, and installation hardware.

When considering installation, if current under sink plumbing is hard copper tubing a Saddle Valve would be used; for flex tubing, the T-Valve would be required.  Please let us know in the notes which one you need. If you do not specify the T-Valve will be shipped


Please Note The Following:  


  • The influent waters psi will have a direct effect on GPD or gallon per day production. The RO is designed to work in a psi range from 35-60 with 60 being optimum. If your water pressure is low or you have a high TDS please consider a system manufactured with a pump.
  • Units are manufactured standard with 110v electrical outlet but are also available in 220v if requested.


C Series

The Thunder C Series uses a Granulated Activated Coconut Shell Carbon (GAC) Filter Cartridge, post membrane cartridge, to remove volatile organic carbon compounds (VOC’s), insecticides, pesticides and industrial solvents

What a deal!!
Style: 6 PACK, Pattern Name: Standard MERV 8
What a value at this price! It's great to have close to a years worth at one time! What I appreciate also, is the durability of the product. Many that I've purchased at a higher cost will start to sag before time is up. I do though, only use for 1 month but I'm sure they can last much longer. Will continue to purchase...

A lot of quality filters for little cost.
Style: 16x20x1, Style: 16x20x1
Been using these for months, great quality. No issues what so ever. I compared price to the 2 main big box stores and this is the best for your bucks. You get a lot more and they are of the same quality. I used to get mine from a big box store with military discount of 10% and this is still a better deal. They fit exactly like the filter I took out, so size is the same. I live FL and run my AC constantly. These last about 2-3 months each. They do no lose their rigidity. They are built with very high quality material. They catch a lot of dust, you can see how dirty they are when replaced. PROS - great quality and last 2-3 months in my AC running constantly - you get a lot for your money when compared to the big box stores - catch a lot of dirt, filters are really dirty after use - very rigid which makes it easy to installation - reinforced wire mesh CONS - None

Top quality filters at a good price.
Style: 20x30x1
These filters are good quality. They are reinforced and hold their shape. They fit perfectly in my filter holder. The thing I like is that the filters were bundled together and shipped in a sturdy box. Other filters I have ordered showed up in a flimsy box and were damaged.

Great Fit and Noticeable Air Quality Improvement
Style: 12x24x1
I purchased the Filterbuy 12x24x1 MERV 8 air filters and have been very happy with them so far. They fit perfectly in my HVAC system without any gaps or issues during installation. After replacing my old filters, I noticed the air in my home feels cleaner and there seems to be less dust settling around the house. They do a good job of capturing everyday particles and allergens while still allowing good airflow. Overall, this is a reliable and cost-effective 4-pack of filters. Solid quality, easy to install, and a noticeable improvement in air freshness. I’ll definitely be ordering again.
