User questions & answers

Question:	How easy is it to clean and how frequently does it need to be cleaned
Answer:	It can be attached to a liter soda bottle. The red protrusion from that end that can be seen in the manufacturers pics is the inlet covered with what appears to be a push fit plastic cap. They come in a sealed plastic bag that I don't want to open till I need the filter. It's probable that some sized hose will fit the inlet when the red plastic cap is removed.
Question:	I don't see in the description where it says it filters out fluoride. That is the biggie for me so curious. I know some Berkeys do just not sure about
Answer:	You can purchase replacement filters for the Outback Plus emergency water system on Amazon under "Outback Plus Water Filter Replacement Kit" or using the following link: https://www.amazon.com/Outback-Replacement-OB-25NF-Emergency-Filtration/dp/B07QMRHPLQ/. Please let us know if we can assist you further.
Question:	are the filters Bpa free? and does Berkey off a ceramic filter for fluoride instead of plastic junk
Answer:	From what I can see, yes... One goes into the refrigerator itself on the back wall and the other above the refrigerator behind the grill ... I change about once a year as I have filtered water as the source for the refrigerator.
Question:	Why is the product Not for sale in California or Iowa
Answer:	Your product should be alright. The water filter is a closed container with a carbon insert, and a cap on to protect the interior. Wipe it off and it is ready to go. The air purifier works by pulling air through the material inside. It is easily protected by the cardboard packaging. You can wipe the dust off, and install it. Should not cause any problem. I did not recall the rattles. I happened to have the last one I replaced since I have not taken it to discard at the local environmental center yet. I shook it and it did rattle. Sounded like some miniature metal balls a bit smaller than the BBs you use to shoot in your Red Rider bb gun when you had a GREAT Christmas years ago. Go ahead and install it and mark your calendar to replace it again in one year. This is about the 14th time I have gone through the process and I think they are very good products.

Product description

INCLUDES: Big Berkey stainless steel housing (Upper, Lower & Lid), 2 Black Berkey Filters, 2 Fluoride Elements, 2 Hole Plugs, 1 knob, 1 easy flow spigot, and 1 set of easy to follow assembly instructions. When drinking water that’s been filtered using a Berkey purifier, you can rest assured that your water is clean and safe for consumption. In fact, Black Berkey purifier elements are far more powerful compared to competitors’ water filters. When tested Berkey water filter elements removed 100% of pathogens, allowing them to be classified as purifiers rather than simply filters. The included two (white) Berkey fluoride filters attach to the bottom of the Berkey Purifiers and hang in the lower chamber. Berkey fluoride filters reduce the amount of fluoride in your water UP TO 95%. Each Fluoride filter has a lifespan of 1,000 gallons and each purifier can filter up to 3,000 gallons. The Big Berkey is constructed from High Grade 304 Stainless Steel, and can accommodate up to four Berkey Purification elements and four Fluoride filters, however only two of each are included with this package.

From the Manufacturer

The versatile Big Berkey system is the ideal system for use at home with small or medium sized families, travel, outdoor activities or during unexpected emergencies. This powerful system purifies both treated water and untreated raw water from such sources as remote lakes, streams, stagnant ponds and water supplies in foreign countries, where regulations may be substandard at best. Perfect for everyday use, outdoor activities and a must in hostile environments where electricity, water pressure or treated water may not be available. The Big Berkey system removes pathogenic bacteria, cysts and parasites entirely and extracts harmful chemicals such as herbicides, pesticides, VOCs, organic solvents, radon 222 and trihalomethanes. It also reduces nitrates, nitrites and unhealthy minerals such as lead and mercury. This system is so powerful it can remove food coloring from water without removing the beneficial minerals your body needs. Virtually no other system can duplicate this performance. Constructed of highly polished 304 stainless steel, the system comes complete with four purification elements and utilizes the latest technological advances. This system has a storage capacity of about 2.25 gallons (8.5 liters) and when in use it stands 19.25" in height with a diameter of 8.5". The upper chamber nests within the lower chamber for transport and stands only 13" in height. Configured with four Black Berkey purification elements the system will purify up to 7 Gallons (13.3 liters) per hour.

Question:	We have a new well and the water has an iron taste as well as staining our toilets, shower pans, etc. We've been using WVC34 filter. Will this help

User questions & answers

Question:	is this model G
Answer:	I'm sure there is. As I recall, the fitting on the filter is a 1/4" push-to-connect tube fitting. You would need to identify the thread on the copper end and buy a fitting with a matching female thread on one end and a 1/4" push-to-connect tube on the other end. Then use a short length of 1/4" polyethylene tube between the two push-to-connects. Take the filter to home depot and ask for help in the plumbing department.
Question:	Can the fxwtc filter be used in place of the fxutc filter
Answer:	It doesn't really need any adaptor. You can cut the existing hose in half, the one from the water source to ice maker. The ends of this filter are made so that you kind of grip and twist to get a nice seal. The directions are good and it is easy. Just make sure you read them....and follow them. :)
Question:	Is this a 2 pack or are there just 1 in the pack at the given price
Answer:	I'm sorry I didn't attempt to do it myself as my fridge/freezer was too heavy for me to move it to get behind it where the filter is attached to the fridge. Someone did it for me. Best get an obliging plumber or builder. It seemed very simple and took only about 10-15 mins. You must turn off the tap first that is connected to the fridge. Then at the fridge end, simply cut off the cable with the old filter - don't try to undo the old filter; it is quite impossible. My fridge has come supplied with a very long cable - enough to have it cut off every six months to replace the filter. The new filter is attached to the fridge cable at an upright position. (You know which way is up from the print on the new filter.) You have to remove the blue clip around the new filter, then insert the fridge cable into it and push as far as the cable will go (about an inch) and then put the clip back to secure the cable. Have a large bowl nearby to catch surplus water dripping out of the old cable. There are instructions with the filter. Get a strong person to do it. Keep the new filter in the upright position behind the fridge with the tape advertised as "no more nails". Buy the red coloured one - not the blue which is not as strong. After connecting up the new filter, you must run the water through the fridge until the water is completely clear. May take several pints. The carbon in the filter will blacken the water and needs to be washed away before ready to drink. To move the fridge without damaging the kitchen floor, use a cardboard sheet under the feet of the fridge to push it out if the fridge is against a wall like mine is. Remember to turn the tap back on once the new filter is secured. Good luck!
Question:	What is the micron ration for these carbon filters (gxwho4f
Answer:	The packaging states it was made in Taiwan.

Product description

The WGB21B is a great "point of entry" filtration system and excellent alternative to the larger WGB22B (4. 5"X20") for smaller homes or where limited space may be a concern. Unlike "point of use" systems the WGB21B will filter water directly from your source. This means that water from every outlet in your home will have passed through this filter, providing up to 50, 000 gallons of clean water for the entire family. The first stage of this system houses a 5-micron high-capacity polypropylene sediment filter (FP15B). This filter is responsible for removing dirt, rust, and most suspended solids, to protect and extend the life of the CTO carbon block filter. The second stage houses the 5-micron CTO coconut shell carbon block filter (FC15B). Block carbon is more effective than other forms of carbon in that it is finely ground up carbon packed into a solidified block. This means they have a higher density than other types of carbon filters, and are therefore more effective in removing their targeted contaminants. The carbon block filter knocks out bad tastes and odors, removes over 90% of sediment and chlorine from the water, and is highly effective on organic chemicals (VOCs) like pesticides, herbicides, and industrial chemicals. If you are on city water, your local water utility must meet very strict Federal and State standards for purity. Almost all municipally treated water is chlorinated, and this can affect taste and create odors in the water. The WGB21B filtration system will remove these tastes and odors. If you are on a private well or spring, you should have your water tested. You may also want to contact our technical staff in Atltant, GA for help in selecting the best filter system for your water chemistry.

• [Two-Stage Effective Filtration] 1st-Stage premium 5-micron polypropylene sediment filter (FP15B) captures dirt, sand, silt, dust, rust, and scale particles and extends the life of CTO carbon block filter. Using high quality coconut shell carbon and highly compact fabrication tech, 2nd-stage CTO filter(FC15B) knocks out cloudiness as well as bad tastes and odors, removes over 90% of chlorine, and is highly effective on VOCs like pesticides, herbicides, and industrial solvents.
• [Superb Filtration Capacity] 10"x4. 5" replaceable whole house water filters can provide up to a full year of clean water(up to 50, 000 gallons) for a family of four. 1-inch inlet and outlet ports allow fast water flow with less pressure loss. Fine PP sediment filter and premium quality CTO filter not only bring clean and fresh water to every faucet in your house, but also help prolong the lives of your water-using appliances and protect plumbing from sediment and scale buildup.
• [Easy Installation and Filter Change] The system comes pre-assembled onto the mounting bracket for a streamlined, DIY installation. Filter wrench included to make routine filter changes easy and quick. A pressure release valve allows for the release of built-up pressure when changing filters. Refer to our manual and/or YouTube videos to Install this point-of-entry (POE) filtration system at the main water supply to get clean and healthy water for the entire family.
• [Top-Notch Customer Service] Backed by a 30-day money-back guarantee. 1-Year manufacturer warranty and extended upon registration at iSpring. Lifetime customer and tech support from Atlanta, GA.
• [TDS Note] Unlike an RO system, this system will NOT reduce Total Dissolved Solids (TDS), and instead keeps healthy minerals in your water. If you are interested in a filter that removes TDS, consider our iSpring Reverse Osmosis (RO) systems.

Frequently Asked Questions

Q: With this whole house system, do I still need to install a water softener if my water is very hard?

A: Yes, a water softener is needed if your source water has a high level of hardness, usually with TDS higher than 700 PPM. Hard water can reduce the lifespan of whole house water filter cartridges. The harder the water, the greater amount of scale buildup occurs, and the sooner the filters get clogged.

This whole house water filter can remove up to 95% of sediment, chlorine, rust, pesticides, herbicides, industrial solvents, VOCs, and various other contaminants that a regular water softener can't, although it does not soften your water. It is recommended that you install this WGB21B series whole house system after your water softener to achieve optimal performance if you have hard water.

To determine which product best suits your needs, it is recommended that you get a professional water test done prior to purchase to identify the main issue of your source water.

Note: Water Softeners and whole house systems usually do not lower the TDS level of the water. An additional Reverse Osmosis system may be necessary for your drinking water. Please consult iSpring professionals prior to purchase if you are unsure of which product will meet your needs.
