Product Details:

  • insulated filter for treating grey water from sinks, showers, and laundry.
  • capacity 600 litres/day/module
  • for summer or winter use and an installation indoors
  • to be installed above ground
  • expandable to suit applications with a pressure water supply
  • domestic, ecological natural filter material


The operation of the Biolan Greywater Filter 125 Large is based on the mechanical and biological filtration of grey water. The organic filter material used in the filter, attracts the phosphates and impurities in the wastewater. The micro-organisms living on the surface of the filter material use the impurities in the water as their nutrition.

The module has ten filter boxes layered one on top of the other. The wastewater enters into the uppermost filter box. Inside the module, the wastewater flows by gravity from one filter layer to the other through the openings in the end each box.  Finally the clean water exists the module and out to a gravel leach bed.

Human waste, storm water or drainage water from foundations must not be fed into the filter. The cleaning capacity of the filter material in the module is good for about 3-6 months depending on volume, after which it needs to be replaced in accordance with the maintenance instructions.  The Biolan grey water filter tolerates a small amount of anti-bacterial and chlorine-based agents that are commonly used for cleaning.  However, toxic chemicals or substances that contain chemicals that can kill the micro-organisms that clean the wastewater, such as drain openers, paints, oils or solvents, must not be fed into the purifier.

Biolan Greywater Filter 125 is an insulated filter module for grey water. The filter is made of frost-resistant materials and is thermally insulated  and can be used with electric cable heaters. The unit operates reliably and lasts a long time.  The filter can be used with a pump, to pump the grey water up to the filter inlet if the grey water is coming from a lower point underneath the building or a basement.

A properly dimensioned, installed and operated Biolan Greywater Filter 125 wastewater system meets the limit values for total phosphorus, total nitrogen and organic material in grey wastewater in accordance with the Ontario building code and the Environmental Protection law (527/2014) and the Decree (157/2017).

Maintenance of the Greywater Filter light

Check the operation of the filter at least twice each operating season. A well-functioning purifier is nearly odourless, the filter material is moist and the water exiting it is clear and odourless and does not contain any significant amount of solid matter.

Check that

  • wastewater is flowing smoothly from all the openings in the box
  • the filter material is a distance of about 5 cm from the openings in the discharge end of the filter tray
  • the purified wastewater is flowing freely out of the filter

Changing the filter material

Normally, the filter material in the purifier must be replaced every 3-6 months of operation. Only filter material specifically intended for Biolan filters is allowed. Biolan does not guarantee the purification capacity of the unit if any other filter material is used.  2 bags of filter material a required to fill the 10 filter boxes.

  1. Change the filter material in all of the filter trays at the same time.
  2. Open the cover of the purifier and lift the filter material trays out of the unit by means of the lifting handle.
  3. Empty the filter material into the compost or use it as cover soil for ornamental plants.
  4. Refill the trays with new filter material. One bag is enough filter material for 5 filter trays.  Rip the filter material loose and spread it evenly across the trays by tapping it gently.  The amount of filter material in the tray is sufficient when its surface lies about 2 cm below the edge of the box. Finally, draw the filter material about 5 cm from the V-openings.
  5. Check the inlet and outlet connectors for wastewater and clean them.
  6. Place the trays filled with new filter material back into the filter unit. The filter material trays are identical, but observe their direction – in the lowermost box water flows towards the outlet connector, in the next box it flows towards the inlet connector etc.
  7. Make sure the unit is in a level position both lengthwise and laterally so that wastewater flows smoothly from one tray to the other.
  8. Close the cover of the filter carefully.
  9. Write down the service measures taken.

The filter material trays are left inside the filter over winter. Freezing of the filter material does not damage the unit. If the filter material is still frozen when the operation starts in spring, thaw it by pouring warm, clear water through the filter.  A heating cable can also be used during the winter to ensure the filter doesn’t freeze.


  • dimensions of the module (width x height x depth): 60 x 123 x 100 cm
  • pipe connectors: for Ø 75 mm sewer pipes
  • height difference of inlet and outlet connectors: 104 cm (height of fall)
  • Canadian Spec capacity: 800 litres/day/module
  • weight without the filter material: 75 kg
  • the distance, travelled by water in the filter material: 650 cm/module

          Estimated Shipping Times-

          If your order is received before noon Eastern Time, your order will typically ship out within 24-48 hours during business hours Mon-Fri.

          home, your nearest neighbour is a penguin, you live in a yurt in Death Valley that only donkeys can reach, or other remote location that delivery trucks
          cannot easily access or are outside of their traditional delivery routes, additional shipping costs may be incurred. We will contact you before shipping your order to confirm if additional charges may apply. We reserve the right to notify you after you have purchased an item of any additional shipping or handling charges necessary to deliver your order. If notified of any additional charges, you also have the right to modify or cancel your order for a full refund.

          Curbside Freight
          Shipment Procedure-

          Most appliances, solar equipment or larger shipment items ship via tractor
          trailer or straight truck and are limited to a curbside delivery. Freight carriers are specially trained and equipped to handle oversized and fragile items safely and efficiently. Please refer to the steps below to know what to expect for the delivery service. Please note that these items cannot ship to P.O. Box.

          Step 1 – Within 24 - 48 hours after your order is shipped you will receive a confirmation email providing tracking information.

          Step 2 – Once the shipment has arrived at your local freight terminal, transport will call you to schedule a delivery appointment. Appointments are made Mondays – Fridays and you are usually given a 4-hour window to expect delivery during business hours. It is important that the phone number provided when ordering is a working number to contact you. If an appointment is not made within a 24-hour period of being contacted, storage
          fees may apply. You would be responsible for these fees.

          Step 3 – Curb side delivery completion –
          The driver will arrive with a lift-gate truck (truck sizes vary) and will lower the order onto the ground at the edge of your driveway. Due to company
          policy the driver is not authorized to move it further. Curbside delivery service does not include set up or assembly of items, or removal of packaging materials, nor does it include bringing the items inside the home.

          Step 4 - Upon delivery, you will need to inspect and sign a Proof of Delivery Receipt for the shipment. Check for visible damage and if any damage is seen make sure that it is noted on the delivery receipt and take pictures of the damage. You have the right to refuse the delivery due to damage shown. For all transport damage issues please contact us immediately. Please note: Shipping is unavailable to P.O. Boxes

          What to know before accepting
          your delivery-

          The Cabin Depot wants to
          make sure your order delivers on time, accurately, and damage free. So, we have some important information about receiving a new order.

          We carefully inspect all
          orders before they leave our warehouse to ensure they are accurate and in perfect condition. If you haven’t received a shipping e-mail confirmation with tracking, and are curious about the status of your order, please let us know at
          any time by calling 

          1-844-603-4743 and
          select option #1

          Whenyour order arrives, you will need to carefully inspect immediately before the truck driver leaves or attempts to have you sign off on the paperwork. Paperwork is normally provided, and your
          signature requested by the driver to acknowledge your order was delivered. If
          they have no paperwork for you to sign (usually a BOL or Freight Bill) you can request it. Some drivers will want to drop your order and leave asap as they
          have other deliveries to make. But remember, you paid to have them deliver your order in perfect condition, and they will wait for you to inspect it. If you sign the delivery paperwork
          without noting any discrepancies or damage, the freight company will not accept a claim and make the customer liable for any damage discovered.

          So, this inspection means that you should: Open all boxes Count all items Ensure the items shipped are the correct model / type / colour.

          DO NOT sign the driver’s paperwork unless you are 100% certain the order is complete, there are no missing items, and it has arrived in perfect condition.

          MISSING ITMES:

           Note exactly what was
          shipped incorrect or missing on your paperwork. You need to clearly write this on the BOL or Freight Bill. Take a picture of the products received, then contact us and we’ll investigate and get this corrected for you asap!


          As upsetting as this may
          be, it does happen on occasion as careless drivers or warehouse workers may have mishandled your order. In this situation, you have 2 options: If there is
          significant damage to the order, you can refuse it. Note “ORDER REFUSED DUE TO DAMAGE” on the paperwork, and make sure you take plenty of pictures of the damage. Then send this information to us so we can follow up with the freight
          company. We can then either refund your order or ship a completely new order to
          you if the product is still in stock and available. If there’s only slight damage to your order, you can still choose to receive it. But note this damage clearly on the paperwork and take several pictures. Then send this
          information to us and we will follow up with the freight company. They would then be liable to provide parts to repair or send you some form of



          This is known as ‘concealed
          damage’ and freight companies only allow 24 hours to file a concealed damage claim. So, it is very important that if you start unpacking your order and
          discover damage to a part that wasn’t visible when you removed the packaging for initial inspection, you need to take pictures and contact us immediately.
          Do not wait. Freight companies will not even consider a concealed damage claim if one is filed more than 24 hours after receipt. Note that concealed damage claims are often denied, which is why your primary inspection as soon as the order arrives is so important.

          Shipping can be expensive, especially when shipping from coast to coast to coast, that's why we believe in being fully transparent about how much you're actually paying for shipping.

          This is why we ask our customers who are interested in purchasing larger items that they fill out a shipping quote request.

          Shipping costs can vary for these larger items and it's not always fair to the consumer to build in "free shipping" costs for these items. This means that you are typically paying more for shipping, and the product, than you should be.

          Some shipping definitions that may help you in the process:

          - Liftgate Service

          This is where the shipping company can lower your items to the ground via a truck "elevator".

          - Appointment Delivery

          This is where the delivery company will contact you when your order arrives at your closest terminal. They will contact you to arrange a block of time, usually a 4 hour window, to deliver your items within.

          - Business Delivery

          This is when your order would be shipped to a business that has loading dock, fork lift or appropriate means of off-loading your shipment.

          Please note that quote requests normally take 24 hours on average to complete, at which time we will contact you by phone or e-mail. Quotes received over the weekend will be replied to on Monday. Some quotes may take longer to process depending on the delivery location and availability of the shipping companies to provide us with quotes.

          Solar to Electrical

          Hi Guys,
          Thanks for this cable. It has enabled me to connect my off-label solar panel to my EcoFlow generator. Here we have been enjoying long sunny days. I have been charging everything in sight. Solid gear.

          Off grid water system

          Works well at our off grid cottage. Pumps water from our brook at a distance of 30ft or from our water tanks to a Camplux water heater. Nice for our outdoor shower or 300 gal tub. Outdoor living at it's finest!

          Falks Propane light

          The light arrived quickly, unfortunately there was a broken part in the box, Cabin Depot's customer service reacted quickly and supplied me with a replacement part

          Q Cells - Bundle of 6 - 480 Watt Q.Peak Duo XL-G10.3 Solar Panels
          Coreen B.

          Excellent quality and all 15 arrived unscathed. Very happy.

          Does everything I expected it to do flawlessly? It’s an excellent unit.


          Great fit and light.

          Dc light- 48 inch

          Easy install. Works well!

          Love my outdoor shower

          I was hopeful that the shower would be what I was hoping for and it exceeded my expectations. We were worried about the psi but it works great. So happy to be able to have a shower at my cabin!

          Perfect fit

          This is the perfect fit for our Osburn woodstove. Best price around.


          The barrel is awesome, exactly as advertised !

          Super Quiet!!

          Really impressed with the customer service and the speed the order got to me. The pump is way quieter than our last one we had.

          Such an upgrade!

          We had a wobbly, half broken, 30 year old stove that leaked. This is 1000 times better! I love how deep it is. It’s just enough that it doesn’t feel like a 24” range and my pans all fit at the same time with its full size cast iron grid. It’s super good quality and it works great. I love the black interior and the finishing touches. So far I’m super excited about it, and by the other reviews I have read, it will continue to exceed my expectations.

          The WonderWash®
          Jennifer E.

          We received our WonderWash last week and my partner did a load of t-shirts and socks that evening. He found that he had to wring the clothing after washing and rinsing. But no worries; back to the internet we go to look for a commercial salad spinner. Otherwise, clothes came clean and fresh smelling. Hung outside to dry. There truly is no smell like the smell of laundry that has been dried outside. We are happy with the WonderWash because we can do a decent load daily or every second day. A ⭐️⭐️⭐️⭐️⭐️ product. My partner even liked the colour of pink WonderWash. 😉

          nice to have a stove even though I don't have electricity. Works and looks good

          Camplux 8L

          Works great as advertised. I bought the Seaflow 3gpm pump and it comes with a strainer and 2 hose attachments. All you need purchase is some 1/2 diameter water hose, 3 smal hose clamps for the water hose and one fitting to go from harden hose thread to a 1/2 diameter nipple.

          Bedroom Ceiling Fan

          We are full time RVer's and have been on the road since 2017, this upgrade was long overdue, since we left our sticks and bricks one of the most missed items was our ceiling fan, on warm nights while boondocking the movement of air makes the difference of enjoying the night or being uncomfortable. We had a 12 volt box fan, and while it moved lots of air it also created lots of noise, we are still working our way through the new fan but the remote is a gamechanger, and while there is some motor noise it is not enough to be annoying.
          We have a 40' motor coach so securing the fan securely was a high priority, only issue will be cabinet door that will require shutting off the fan to access but a small price to pay for the added comfort and to be able to run the fan directly off of our lithium batteries is a bonus.
          The only negative so far was the inline glass fuse that made it difficult to install the motor cover as it has to be maneuvered over the motor housing while the motor was secured to the ceiling.
