Best CPAP Machine Buying Guide + Reviews

More and more people get diagnosed with OSA, obstructive sleep apnea, a condition that is defined by a blockage in the airway at the back of throat, causing difficulty in breathing and inability to sleep comfortably.

Most patients with this condition snore heavily during sleep, and can experience temporary periods of difficulty in breathing. This normally disrupts sleep and could cause major sleepiness during the day, a symptom that could affect a person’s daily health and quality of life. Other complications include headaches, mood swings, and high blood pressure.

Positive Airway Pressure devices (PAP) such as the continuous PAP (CPAP) and the bi-level PAP (Bi-PAP) are therapeutic devices that help patients with sleep apnea to sleep smoothly all through the night.

Types of PAP Machines

There are three types of PAP machines and they include the CPAP, APAP and Bi-PAP.

CPAP

CPAP stands for Continuous Positive Airway Pressure. It is the most frequently used treatment option. It delivers constant and pressurized air into the airway.

APAP

APAP stands for Automatic Positive Airway Pressure. It is a non-invasive treatment that transfers pressurized and unclogged air through a mask during sleep. It has two range settings, low and high, that regulate automatically using an algorithm based on the user’s needs.

Bi-PAP

Bi-PAP machines are a non-invasive treatment with two pressure settings, one for inhalation and one for exhalation. It is used to treat patients who express difficulty while breathing.

Cheap or Expensive CPAP Machine?

Selecting a proper CPAP machine is critical towards effective treatment therapy, and cost is one of the important factors that will influence a buyer’s choice. Second hand and discontinued machines are the least expensive, and are designed to last up to 5 years. You could be buying a second hand machine with not much life left, and does not have any form of warranty from the manufacturer. Discontinued machines are heavily discounted by suppliers to clear their inventory. Most modern types have a reasonable useful life span of 5 years, and come with removable components that you need to replace. You need to ensure that the replacement pieces will be available during the 5 years.

Expensive machines on the contrary, are mostly new, have a form of warranty and customer support, and are built with the latest technology to automatically adjust to the user’s needs.

Today, the two leading manufacturers of CPAP machines are Resmed and Philips Respironics. CPAP machine features range in price, you need to decide which one to purchase for a successful therapy.

Should you buy a CPAP Machine using Cash or Insurance?

The best CPAP machines in the market are a bit pricy, but you need a machine that is going to deliver successful therapy. Below are a few factors to consider when deciding whether to using insurance, or out of the pocket:

Compensation by Insurance

If the CPAP supply is refundable by the insurance company, then it is a good alternative to save money, but if it is not, then cash is the other only option. Most health insurance companies cover the CPAP machines.

High deductible vs low deductible plan

High deductible simply means lower monthly premiums, and that some benefits are covered before you settle your deductible. If you have a high deductible, it is advisable to pay in cash especially if you have not met, or not even close to meeting your deductible, because cash prices are more economical than insurances prices.

On the contrary, it is better to use the insurance plan if you have a low deductible plan.

Status of your insurance plan

What is the status of your insurance plan? Have you met your deductible? If you have not met your deductible then pay in cash, if you have, make use of the insurance and get the most affordable price. If you are close to meeting your deductible you could also make the purchase using insurance. However, this depends on the price of the product you are purchasing. In case the product costs less than the outstanding balance on your deductible, like a CPAP mask for instance, then you will fetch the best price paying out of the pocket. If the product costs more than the unsettled amount on your deductible, like the CPAP machine itself, you would economize more using your insurance.

If you have do not have insurance then the only option is paying through cash. Some people may prefer paying in cash anyway to avoid taking on other insurance stuff such as co-insurance. Some insurance companies might provide a selection of providers to deal with that you may not be contented with due to various reasons like location, product options etc.

Important Features of a CPAP Machine

Here is an overview of the important features of a good CPAP machine from their power options, warranty policies to the technological aspect;

Power alternatives

Standard CPAP machines often do not come with an integrated battery. Here are a few options to power up your CPAP machine in case you lack a power source;

  1. Batteries

Most CPAP machines integrate battery kits. Battery department stores have manufactured universal battery kits to fit all types of CPAP machines. Resmed and Philips Respironics have come up with their own kits specially for their machines. The batteries can keep the charge for 1-2 days, while the deep-cycle marine battery can store charge for up to 3 days. The batteries can be recharged in different ways but the most common is using the DC outlet.

Solar energy

Solar power is an option to recharge your battery it especially when going off the grid. You must leave it in the sun for at least 6 hours, and is perfect when going camping.

DC Power Cord/ Inverter/Converter

A DC power cord can be connected to the CPAP machine if it has a DC outlet. You can use A DC adapter cable to offer power directly to a deep cycle marine battery. You will need an inverter or converter to convert the DC power to AC power if you do not have the DC outlet.

Adapters have become a necessity when traveling with a CPAP machine that sources its power from a battery.

Nevertheless, manufacturers have made intergrated batteries for travel CPAP machines for example the Transcend. They do not need additional cables or inverters to recharge. They directly affix to the CPAP machine and use the same cord the machine uses for charge, and is portable for use once the batteries are charged fully.

Warranty policies

One factor to consider before purchasing a CPAP machine is the duration of the warranty. Most warranties last 2 years (for example Resmed and Philips Respironics), others last 3 years. Most humidifiers have a 1 year warranty, some 2.

Another important factor is the convenience and reliability of the warranty service. With some manufacturers you can exchange your faulty machine with a new functional one, without any waiting time. Some manufacturers though, will give you a refurbished one in the place of a brand new one. It is paramount that you check the manufacturer’s warranty policies before purchasing the product.

Technological aspects

Auto start/stop- most CPAP machines can recognize when someone puts the mask on and starts breathing, so they start up automatically. They also stop automatically when someone takes off the mask.

Auto detects pressure– all APAPs have this characteristic. CPAP machines checks your sleeping performance as you breathe, looking out for apneas, flow hindrances etc. while adjusting the pressure level consistently.

Pressure relief during exhalation– modern CPAP machines can imitate the natural breathing sequence by decreasing the pressure level at every exhalation. This alleviates the alteration between inhaling and exhaling, making the therapy comfortable for the user.

Mask fit check- most CPAP machines detect when a mask fits perfectly or not. You can adjust the mask before therapy begins.

Leak compensation- this is where the level of pressure is increased when there is a leak. This ensures that you can continue with your therapy even when a leak occurs.

Heated hose– it keeps the humidity warm, making it more enjoyable breathing. It is a comfort feature that some CPAP machines have.

Data tracking- you can check all kinds of information like usage hours etc.

Ramp feature- ramping is when at the start of your therapy pressure levels are low, and systematically increases with time. This feature is meant to make it easier to fall asleep while on therapy.

Bluetooth- allows the user to connect to apps.

Factors to consider when buying a CPAP Machine

Here are the factors to consider when shopping for a CPAP machine;

Design

Modern designs look sleek and defined. Common ones are huge and difficult to carry around.

Performance

Is it reliable and efficient? A good machine satisfies the purpose to which it was meant to serve.

Features

There are important features to look at, does it have the auto feature, leak compensation, does it have the mask on/off alert, is it portable, does it have the ramping feature, is the humidifier intergrated or separated.

Power

Does it have long lasting battery life? Does it have several plug-in adapters? Can it use a portable battery?

Noise level

The sound it produces should be as low as a whisper. Anything louder disrupts sleep.

Is a humidifier necessary?

Humidifiers are not just an accessory. A heated humidifier turns heated water to humidity and delivers it through the airway. Throat dryness is one of the most common side effects of the therapy, and humidifiers play a huge role in resolving irritation. Patients above the age of 60, those undergoing more than 2 medications and those with chronic mucosal disease however need a humidifier.

During seasons with high humidity you may not need a humidifier.

You may need heated tubing for a heated humidifier to prevent rainout caused by condensation in the tubing.

Saline sprays are a good alternative for humidifiers.

Humidifiers should be cleaned regularly to keep you from the risk of infection around the area. Also fill it up with fresh water every day for hygienic reasons.

Types of hoses

A CPAP hose is a tube that delivers airflow and is used to connect the machine to mask, humidifier to mask and machine to the humidifier. There are two types of hoses, heated hoses and unheated hoses.

Heated hoses

Unheated hoses

If you undergo sore throat or dryness during CPAP therapy, then heated hoses and humidifiers could be beneficial. An unheated hose could cause a rainout due to the difference in temperature outside and inside the tubing, which could run into the user’s face, or dampen the bed.

Additionally, covering a hose enhances the outcome of a heated tubing. Hoses should be cleaned often, using cpap cleaning system or mild soap and warm water, then air it out to dry. In case of any breakage, you should replace the hose immediately.

There are a few other alternatives to consider while treating sleep apnea. One of them is simple, pillows. Pillows play a major role in placing your head and neck on a comfortable position to reduce interruptions caused by sleep apnea during sleep. They tilt the head in manner to control obstruction of the airway while sleeping and helps people with minor sleep apnea. Adjustable beds also play a role in ensuring comfort during therapy. Lifestyle changes also play a big part in ensuring a healthy living with sleep apnea. Habits such as smoking should be avoided by people with sleep apnea as this contributes to blocking the airway. Weight loss also contributes to eliminating obstructions in the airway and these two practices should be embraced by people with this condition.

Sleep apnea is a treatable condition. Developments have been made over the past few decades and modern technology is being used to produce better high quality CPAP machines, with much consideration on reducing the size and the noise level to make it quieter and more comfortable for users. It is important to consult a medical doctor or physician before starting or altering any treatment choices.
