Looking for trusted CPAP Singapore guidance? This beginner’s guide explains CPAP, APAP, and BiPAP, helps you choose the right mask, and covers essential accessories and care—so you can start therapy confidently.
How CPAP Therapy Works: The Science Made Simple
Sleep apnea causes your upper airway to narrow or collapse during sleep. Continuous Positive Airway Pressure (CPAP) therapy is the gold-standard treatment that solves this problem.
A CPAP machine is a quiet, gentle blower that sends a steady stream of pressurized air through a tube to a mask you wear at night. This constant pressure acts as an “air splint,” keeping your airway open and allowing you to breathe continuously. The result? No more snoring, no more choking, and a dramatic drop in your Apnea-Hypopnea Index (AHI)—often by a factor of ten or more.
While “CPAP” is a general term, there are several types of PAP machines available. To see current models and prices in Singapore, explore our CPAP & BiPAP collection or our 2025 buyer’s guide Where to Buy CPAP Machine Singapore (2025).
APAP (Auto-CPAP): Auto-Adjusting for Your Needs
The modern Auto-CPAP (APAP) is the most common machine prescribed today. Instead of a single fixed pressure, it operates within a prescribed range (e.g., 4 to 20 cm H2O). The machine’s algorithm detects when you are having a breathing event and automatically increases the pressure to open your airway. Once the airway is stable, it may reduce the pressure to improve comfort.
If you prefer a smooth, value-for-money APAP experience, consider the Resvent iBreeze Pro Auto CPAP. You can also compare options in our shop collection.
BiPAP (Bilevel): When Two Pressures Are Better Than One
A Bilevel (BiPAP or BPAP) machine offers two distinct pressure settings:
- IPAP (Inspiratory Positive Airway Pressure): A higher pressure delivered when you inhale.
- EPAP (Expiratory Positive Airway Pressure): A lower pressure delivered when you exhale.
The difference between these two pressures is called Pressure Support (PS). This drop in pressure during exhalation makes breathing feel much more natural and comfortable, which is why 9 out of 10 patients I work with prefer BiPAP over CPAP. It’s especially beneficial for those who struggle to exhale against a constant high pressure or require very high treatment pressures.

Does the CPAP Machine Brand Matter?
While many brands exist (ResMed, Philips, Löwenstein, Resvent, BMC), the most important factor is breathing comfort. Each machine has a unique pressure-delivery algorithm. Some can feel more aggressive, while others feel smoother.
My #1 advice: Don’t buy a machine online without trying it first. A good equipment supplier will let you lie down and test different machines and masks with the pressure running. It’s like test-driving a car—you need to find the one that feels right for you.

How to Select the Perfect CPAP Mask
Choosing the right mask is critical for success. The goal is to find a mask that is both comfortable and provides a good seal. My recommendation is to always start with the smallest, least-invasive mask style possible and only move to larger masks if necessary.
| Mask Type | Description | Best For | Popular Examples |
|---|---|---|---|
| Nasal Pillows / Prongs | Small silicone pillows that seal directly at the nostrils. Minimal contact. | Smaller, flatter noses. Active sleepers. Many Asian users. | Philips DreamWear Silicone Pillows (see CPAP masks collection) |
| Nasal Cushion | A soft cushion that seals around the base of the nose without entering the nostrils. | Larger, longer noses. Users who dislike prongs. | Under-the-nose styles (browse nasal cushion masks) |
| Nasal Mask (Triangular) | Covers the nose from bridge to upper lip; indirect pressure, traditional fit. | Users preferring a classic, stable seal. | Philips DreamWisp |
| Full Face Mask | Covers both the nose and mouth (does not cover the entire face). | Elderly users, mouth breathers, slack jaw, or severe nasal obstruction. | View options in the full face masks section |

Essential CPAP Accessories Explained
Humidification and Heated Tubing
Always get a machine with a humidifier. CPAP air is dry and can cause throat and nasal irritation. A humidifier adds moisture, making therapy significantly more comfortable. Pair it with a heated tube. This feature keeps the air warm all the way to your mask, preventing condensation (“rainout”) from forming inside the tube and splashing your face.

Filters and Maintenance
Your machine will have at least one reusable filter that protects the motor from dust.
- Check weekly: If you see dust, wash with soap and water, let it dry completely, and reinstall.
- Replace every ~6 months or when it looks worn.
- Some machines also use a disposable ultra-fine filter for cleaner air—replace monthly.
