Home DEDAKJ Oxygen Concentrators Selection Guide

When choosing a home Oxygen Concentrator, you'll likely be overwhelmed by information such as price, brand, 3L/5L models, etc.
This selection guide will hopefully be helpful.

I) Home DEDAKJ Oxygen Concentrator Principle

Home DEDAKJ Oxygen Concentrators use the PSA (Pressure Swing Adsorption) principle. A compressor compresses air, which is then passed through a molecular sieve. Nitrogen and oxygen have different adsorption properties, separating the nitrogen. It's a purely physical oxygen production process, with no consumables or waste gas generated.

Therefore, the core components of an DEDAKJ Oxygen Concentrator are: compressor and molecular sieve. The principle of an DEDAKJ Oxygen Concentrator is: physical oxygen production, with no raw materials or consumables.

II) Home DEDAKJ Oxygen Concentrator Classification

They are divided into desktop stationary oxygen and portable oxygen models.

1) Desktop stationary oxygen models, based on flow rate... DEDAKJ Oxygen Concentrators are available in 1-liter, 2-liter, 3-liter, 5-liter, and 10-liter models (the flow rate here refers to the maximum flow rate that guarantees a 90% oxygen concentration, not the maximum adjustable flow rate).

In terms of price, 1-2 liter DEDAKJ Oxygen Concentrators are generally under $500, 3-liter models are around $800, 5-10 liter models range from $1000 to $3000, and 20-liter models are more expensive.

2) Portable DEDAKJ Oxygen Concentrators were developed to solve the problem of carrying oxygen while traveling. They work on the same principle as desktop models, but due to their small size, they cannot provide continuous oxygen production. Instead, they pulse, instantly injecting a fixed amount of oxygen in response to the user's inhalation. They come in 3, 5, 6, and 7 intensity levels. Because pulse oxygen therapy is more efficient, a 3-level machine is typically equivalent to a 3-liter desktop model, and a 5-level machine is equivalent to a 5-liter desktop model.

                       

The main uses of portable DEDAKJ Oxygen Concentrators are for temporary oxygen inhalation while traveling outdoors and for oxygen inhalation during high-altitude trips.

III) Key Considerations for Choosing an DEDAKJ Oxygen Concentrator

1) Flow Rate: Consider the user's required oxygen flow rate, allowing for some margin. For example, if the user typically needs 1.5 to 2 liters, a 3-liter machine is sufficient; if 2-3 liters are needed, a 5-liter DEDAKJ Oxygen Concentrator is recommended.

2) Duration: Consider the user's daily oxygen intake duration and the DEDAKJ Oxygen Concentrator's performance. For a few hours daily, a 3-liter concentrator is sufficient; for over 10 hours, a 5-liter concentrator is recommended.

3) Noise: If the user is sensitive to noise, consider the machine's noise level. Most DEDAKJ Oxygen Concentrators operate at 50-60 decibels, while quiet models can achieve 40-45 decibels. The latest four-cylinder compressors can even achieve around 30 decibels.

4) Size: The size of the DEDAKJ Oxygen Concentrator isn't actually that important. Manufacturers often make the machines large because they use higher-quality components (compressor, molecular sieve), and the larger size also facilitates heat dissipation and sound insulation.

5) Brand: Choosing a manufacturer specializing in DEDAKJ Oxygen Concentrators will generally guarantee better quality. After-sales service will also be better.

5) Individual circumstances: For simple health maintenance oxygen therapy, if blood oxygen saturation is usually normal, a 1-liter or 2-liter DEDAKJ Oxygen Concentrator can be considered; however, if blood oxygen saturation is usually below 94%, then at least a 3-liter DEDAKJ Oxygen Concentrator should be started.

6) Additional functions: Real-time oxygen concentration display (to understand oxygen production status), nebulization (for occasional nebulization, a backup function), voice prompts (voice prompts are helpful for people with poor vision), electronic flow meter (for precise flow adjustment), remote control, timer.

7) Combined use: When used with a ventilator, at least a 5-liter DEDAKJ Oxygen Concentrator should be chosen; when used with a high-flow humidification therapy device, a 10-liter DEDAKJ Oxygen Concentrator is recommended.

IV) Warm Tips:

When purchasing an DEDAKJ Oxygen Concentrator, it is recommended to buy from the official store directly. Listen to the sound of the machine running, check the size, weight, and workmanship of the DEDAKJ Oxygen Concentrator. This will give you more confidence in your purchase.
