Will it damage my washing machine?
We haven’t had that issue, but if it’s something you’re worried about, here are some suggestions. First, we recommend not washing your AirThreds with delicate items. If you don’t want to wash it by itself, throw it in with jeans or towels. Second, you can “pre-treat” by running your vacuum hose over your filter to remove excess contaminants. This is also a great solution for a quick clean between washes!

Does this help against Virus?
AirThreds filtration efficiency is based on Ashrae 52.2 Merv 8 Standards. Our furnace filter will not filter viruses, however, Airthreds filter will be able to filter some of the particles in the air that carry viruses, and bring you cleaner air

How effective it remains after multiple washes?
There are two parts to this answer: The two components that can wear down in an AirThreds filter are the anti-bacterial coating and the mesh that the filter is made from. Trust us though, they’re both tough! Our studies have shown that after 35 to 50 washes, the coating still maintained itself on average 80%. In terms of the mesh, testing shows that our premium German fabric is altered only 0.8% after 10 washes.

Are these manufactured in the USA?
We are headquartered in Denver, CO, where we do all of our product design and development. We outsource the manufacturing so we can offer AirThreds at the best possible price to our customers.

Is there a lifespan on this filter? How many times can I wash it?
We recommend purchasing a new AirThreds filter after 36 to 50 washes to maintain maximum efficiency.

Why should I use Merv 8 instead of a higher Merv like Merv 11?
Most systems can handle up to MERV 11 without any major issue. But using single-use filters, at higher MERV level, can be expensive. If you need a higher filtration level like MERV-11 or above, then AirThreds is probably not the right product for you. Most people use a MERV-8 in their homes and replacing the filter every one to three months. Airthreds can help to reduce that cost and the added waste that ends up in our landfills.

Do you have MERV 13 available?
We don’t currently, but at AirThreds we are constantly developing new products. A higher MERV rated filter is currently in R&D.

can you stack two filters for a two-inch filter height (or three for that matter)
Theoretically yes, you can. However, we have not evaluated this in our lab testing.

What’s the rating after a few washes?
The Merv rating will remain the same up to as many as 36-50 washes.

Will airthreds restrict airflow?
AirThreds is a lab tested Merv 8 filter that has the same airflow pressure drop as regular filters. Most HVAC systems in the residential and light commercial markets are designed to move 900 to 2000 cubic feet per minute (CFM) at a total system static pressure of approximately .5 to .7 WG total pressure drop. AirThreds maximum pressure drop is 0.68 WG.

Do you make customize sizes?
While we don’t have custom filters at the present time, we are currently developing more standard sizes. In the meantime, we offer six standard sizes that will hopefully meet most of our customers’ needs.

Do you have thicker sizes?
At the present time, AirThreds is offered only in a one-inch thickness.

Can it be cut down to use in smaller ducts?
Unfortunately airthreds cannot be cut down or resized since our product is made of two parts: the frame and the filter, and the frame’s size is unmodifiable. We are currently developing more standard sizes to meet more needs.

I pledged for add-ons on Indiegogo but they aren't on my pledge.
If you pledged for any add-ons through Indiegogo you will see credit equal to the amount of your add-on(s) minus shipping, please don’t forget to pick them out through the BackerKit add-on store! We didn’t charge for shipping through the campaign and charging here, through the survey. You will only owe for shipping at the end of the survey after picking out the add-ons.

Why do I have more than one survey?
If you pledged for two or more main perks on Indiegogo they are imported the same way and create multiple surveys. It is necessary to fill them all out to claim all your rewards.

What is BackerKit?
BackerKit is a service that crowdfunded project creators use to keep track of hundreds to tens of thousands of backers—from shipping details, pledge levels, preferences and quantities, whether they have paid or had their card declined, special notes, and everything in between!
The BackerKit software and support team is independent from the campaign’s project team—BackerKit does not handle the actual reward shipping. For more information about the preparation or delivery status of your rewards, please check the project's updates page.
How does BackerKit work?
After the campaign ends, the project creator will send you an email with a unique link to your survey. You can check out a walkthrough of the process here.
I never received my invitation. How do I complete the survey?
The most common reasons for not receiving a survey email is that you may be checking an email inbox different from the email address you used to sign up with Kickstarter, Indiegogo or Tilt Pro account, or it may be caught in your spam filter.
Confirm that the email address you are searching matches the email address tied to your Kickstarter, Indiegogo, or Tilt Pro account. If that doesn’t work, then try checking your spam, junk or promotions folders. You can also search for "backerkit” in your inbox.
To resend the survey to yourself, visit the project page and input the email address associated with your Kickstarter, Indiegogo or Tilt Pro account.
How do I update my shipping address?
BackerKit allows you to update your shipping address until the shipping addresses are locked by the project creator. To update your address, go back to your BackerKit survey by inputting your email here.
When will my order be shipped, charged or locked?
That is handled directly by the project creator. BackerKit functions independently of the project itself, so we do not have control of their physical shipping timeline. If you want to check on the project’s status, we recommend reading over the project's updates page.
I completed the survey, but haven't received my rewards yet. When will they arrive?
As BackerKit does not actually handle any rewards or shipping, the best way to stay updated on the shipping timeline would be to check out the project's updates page.
