Q: Why is the Steam Key of Filament safer than the account format?

The Steam Key format is what we always recommend due to its ease of use and higher security compared to any other format. You just need to redeem the key in your account to download Filament to your game library. The account format requires more complicated steps and is more prone to errors during activation.

Official stores are authorized distributors, and while their prices may be higher than Key stores, their reliability is 100%.

“Choose it if you don’t mind the price difference”

Key stores are resellers and marketplaces, which is why they are usually cheaper than official stores. We only show the best ones, so you can rest assured. Plus, we offer our guarantee against any issues.

How much does Filament for PC cost right now?

Filament for PC starts at €2.19 at Instant Gaming, a Steam key.

With 15 offers across 10 stores there is enough competition for the price to move, so the gap between the cheapest and the rest is worth checking before you buy.

Is it worth buying the Steam Key for Filament now or waiting?

That €2.19 key is at one of its best prices.

Those €2.19 are 50% below what it usually costs, measured on the store price.
10 stores sell the Steam Key at the same time, and with that much competition the price moves almost daily.
Not counting today, only 388 days out of the 1,650 days on record were this cheap or cheaper; the lowest it has ever cost is €1.74.

At this price it is worth buying the Steam Key now: what you stand to gain by waiting is a few euros, and it is not guaranteed.

Worked out from 2,744 daily records of the Steam Key for Filament across 18 stores. See the full price history.

The price does not include each store's payment fees. The percentage is measured on the store price, without coupons, because that is how we record the history. The analysis only counts Key offers. Shared accounts, Steam Gift and physical editions stay out, because they are not the same product and their prices move differently.

Which Filament editions are on sale?

Beyond the standard edition at €2.19, there is the Special at €15.38 at GamesPlanet, €13.19 more. Check on the store what each one adds before paying the difference.

Can you activate Filament in US?

13 of the 15 offers work on US — the Global ones plus the ones issued for your own region.

Is Filament worth it?

Critics put it at 80 out of 100, though there are only 17 reviews published so far.

Why is there such an expensive Filament offer?

One listing is worth ignoring: the Steam key that GamersGate has at €19.50 is more than 8 times the cheapest offer and is not what this game costs. The number to work from is €2.19 at Instant Gaming.

What is Filament's cd key?

The cd key is a digital code that will allow us to download the Filament game in digital format from the Steam game platform.

Don't forget that from Gocdkeys we show you a price list in which you can find the store that sells Filament at the cheapest price. We also want to remind you that these digital keys can be regionally blocked, so find out about possible geographical restrictions before buying in each of the stores.

How can we find the cheapest price for Filament cd key?

From Gocdkeys we offer a comparison of prices and stores that sell the digital version, in key format or Filament cd key. Simply enter the list and you will see all the prices ordered from lowest to highest, so it will be easier to find the best deals and prices.

You can use our filters to filter by versions or activation regions, to make it easier for you to find the cheapest Filament edition that best suits your needs.

What digital versions of Filament can we buy?

Although from Gocdkeys we indicate that it is the cd key, it can also be available in "Steam Gift" format which means that instead of receiving a code or digital key after the purchase, we will receive an activation link, which will activate the game directly in our game library. Steam Gifts can be regionally locked, so please pay attention before purchasing this version.

Before buying Filament you should know that...

Get on board the Alabaster, one of the flagship research ships of The Filament Corporations, and try to regain control of a mysterious complication that left the ship locked up and the crew missing. With only Juniper's help, the pilot affected by the ships faces devilishly difficult puzzles that will push him to the limit in an attempt to discover what happened to the crew and why they disappeared.

A single player game with complex but highly addictive puzzles, challenge yourself to board the Alabaster and then challenge yourself to leave. Freely explore the ship and solve over 300 challenging and varied puzzles

Most common FAQs when buying Filament for PC in digital format:

It is a key that will allow you to download the game Filament on your PC from official download platforms.

As of 23/08/2026, in United States, the best price we have found in our selection of online stores that include the key for Filament on PC is €2.19.

The Steam Key format is what we always recommend due to its ease of use and higher security compared to any other format. You just need to redeem the key in your account to download Filament to your game library. The account format requires more complicated steps and is more prone to errors during activation.

The only issue we’ve encountered in 13 years is receiving a duplicate key that doesn’t work. In that case, simply contact the store where you bought Filament, and they will provide a new key. You can also contact us, and we’ll help you out.

Delivery times vary by store. For example, in the case of Instatgaming, Eneba, G2a, or Kinguin, delivery is usually instant or takes just a few minutes. These stores rarely delay game deliveries.

Other stores may take 30–40 minutes depending on game availability. On release days, delivery times may be slightly longer.

If you notice an unusually long delay, contact the store or us, and we’ll resolve it as quickly as possible.

At Gocdkeys, we only list the most well-known stores that have passed our quality checks. One of the most important factors is good customer support, and all listed stores offer it.

There have been occasions when those services were overwhelmed, which is why we also offer 24/7 customer support to help resolve any issues or questions.

In any case, we always offer a 100% guarantee, so you won’t have any problems, and if you do, we’ll resolve them as soon as possible.
