What’s the real difference between a €3.000 booth and an €8.000 soundproof booth? What features should you demand? What red flags should you avoid?
If you are looking to invest in soundproof booths or office pods, this series of blog posts was written for you.
Over four posts, we’ll explain different aspects of booths in simple to understand language, covering all the key aspects from soundproofing and ventilation to comfort and durability.
We’ll show you how booths are built, how different manufacturers make different engineering decisions. We’ll even tell you how some manufacturers cut corners to save money. And then we’ll show you how to spot it before you part with your own money.
At Persy Booths, we make booths. It’s in our name. But we’re not telling you which booths to buy. We’re just giving you the information so you can make that call for yourself.

In this short article, we’ll cover
• Why ventilation matters
• How it works
• What to look for
The truth about ventilation
While having a soundproof booth is great, it’s not going to get used much if it gets stuffy inside and you won’t get the most from your investment. Note that temperature and CO₂ levels affect concentration too, so good ventilation is essential. If the air within the booth is replaced every 30–40 seconds, you should have a place that’s equally good for quick calls or longer work sessions.

Fan power
Virtually every soundproof phone booth in the market uses fans to power their ventilation, but there’s a huge variance on how they do it.
The best booths will use two or three fans; the cheapest may try to get away with just the one. Higher-quality booths have more fans for two reasons: they want to ensure a healthy supply of fresh air to keep it comfortable, and the soundproofing measures mentioned earlier restrict the flow of air and thus need more fan power to keep the air flowing through the system.

What to look for
• More than one fan per square meter
• Air replaced every 30–40 seconds
What to avoid
• One fan (or less) per square meter
• Air replaced every 60+ seconds
A rule of thumb...
If the air isn’t being replaced every 30–40 seconds, the booth will feel uncomfortable faster than you expect.

•Ventilation directly affects comfort, focus, and how often people actually use a booth.
• A high-quality booth should fully replace air every 30–40 seconds.
• Better soundproofing requires stronger ventilation systems and more fan power.
• Quality booths typically use two or three fans instead of just one.
• Poor ventilation quickly leads to discomfort, heat, and rising CO₂ levels.
• The easiest way to evaluate ventilation is to spend several minutes inside the booth yourself.
Ventilation might not be the first thing you think about when comparing booths, but it has a direct impact on how usable the space really is. If people don’t feel comfortable inside, they simply won’t use it.
We’re not telling you that Persy Booths is the best, most perfectly ventilated option for you. You can make your own decision – we’re just trying to give you the facts you need to make it.
