## Frequently Asked Questions
**What is the difference between cleaning and disinfecting books?**
Cleaning (dust removal) serves to remove external dust from books, preventing them from deteriorating over time. Disinfection, on the other hand, targets bacteria, mould and viruses.
👉 This is why the two processes are separate:
- Depulvera®, Pulvisina®, L’aura® → cleaning
- Nebula → disinfection
**Which machine should I choose for the daily cleaning of large quantities of books?**
If the aim is to process large volumes quickly and efficiently, the solution is an automatic machine.
👉 Depulvera® is designed for:
- fast cleaning (up to 12 books per minute)
- continuous use
- preventative maintenance of collections
**I have a small library or a limited budget: which solution is best suited?**
A full automatic system isn’t always necessary.
👉 Pulvisina® is ideal for:
- small libraries
- cleaning before/after lending
- spaces with limited room
**I need to clean archives, files or large-format materials: which machine should I use?**
Archival materials have different requirements to books.
👉 L’aura® is designed for:
- folders and archival documents
- large-format books
- non-standard materials
**How should antique books, manuscripts or fragile materials be handled?**
Historical or damaged materials must not be placed in automatic machines.
👉 Spirabilia® is the right solution for:
- antique books (even from the 4th/5th century)
- manuscripts and rare materials
- museum objects and delicate collections
It is a manual workstation designed for conservation.
**Can the inside of books also be cleaned with these machines?**
Internal cleaning (between the pages) is a complex process and is not always recommended.
👉 The correct approach is:
- automatic external cleaning → Depulvera® / Pulvisina® / L’aura®
- targeted internal treatment → Spirabilia® (manual and controlled)
This ensures the safety and preservation of the material.
**When is it necessary to use a disinfection machine?**
Disinfection is necessary when the following are present:
- mould
- bacteria
- biological contamination
- health requirements (e.g. after frequent use)
👉 Nebula uses a controlled treatment with biocidal compounds (QAC) and automatic drying.
⚠️ Important: disinfection must always be carried out after cleaning.
**Is there a single solution that combines cleaning and disinfection?**
From a conservation perspective, it is preferable to keep the two processes separate.
👉 The correct workflow is:
- Cleaning → dust removal
- Disinfection → microbiological treatment
This ensures:
- greater effectiveness
- less stress on materials
- better long-term preservation
**How do I choose the right machine for my specific situation?**
The choice depends on three main factors:
- Volume of books
- Type of material (modern, archive, antique)
- Objective (prevention, conservation, disinfection)
👉 In summary:
- Large volumes → Depulvera®
- Small collections → Pulvisina®
- Archives → L’aura®
- Rare materials → Spirabilia®
- Microbiological issues → Nebula
