Home Oxygen Concentrator Buying Guide - How to Buy a Home Unit (1)

This guide will tell you what to know if you're searching for a home oxygen concentrator (HOC). Here, you'll learn how HOCs work, which features to look for, and get a comparison of some of the most popular HOCs.

How do HOCs work?

HOCs are large, stationary machines that are not meant to use as portable devices but offer supplemental oxygen around the clock. However, some machines can be easily moved around the home from room to room. If you're after portability, consider a portable oxygen concentrator (POC).

HOCs do not require much energy, oxygen tanks, or batteries. These machines generally only increase an electric bill by 5-10 percent.

Home oxygen concentrators work like POCs. They take in air from the room, filter it, and separate oxygen molecules from nitrogen and other trace gases, delivering oxygen to you via nasal cannula or mask. Unlike POCs that generally offer pulse dose oxygen delivery, HOCs provide a continuous flow of oxygen.

Room air consists of about 21 percent oxygen, about 78 percent nitrogen, and trace amounts of other gases. Once HOCs do the job of filtering out other gases, they deliver additional oxygen to patients. The higher your machine's liter flow, the more oxygen you'll receive. For example, if your prescribed flow is 2 liters per minute, you'll breathe 28 percent oxygen instead of the 21 percent you'd get from breathing room air. How many liters per minute you'll set your device to depends on the prescription from your doctor.

HOC Features to Consider

When shopping for a HOC, consider these features while comparing machines.

Liter Flow

When comparing HOCs, you'll need to ensure your unit meets your supplemental oxygen needs, so check your prescription first. The prescription from your doctor tells you how many liters per minute you require. Two liters per minute or less is typical, but some require higher oxygen flows. If you wear 2 liters per minute around the clock but feel short of breath during activities, you might need to increase your flow. Therefore, purchase a device that offers higher flow settings, and always check with your doctor before increasing your oxygen.

Power Consumption

Like other home appliances, HOCs use energy from a wall outlet, and the amount of energy used varies by machine. Usually, units that deliver higher oxygen flows use more power. When shopping for your HOC, ensure it meets your oxygen needs, rather than purchasing a device based only on low power consumption.In addition, some manufacturers offer consumer-grade batteries, which helps during a power outage.

Weight and Transportability

Home concentrators weigh more than portable oxygen devices but typically offer higher oxygen flow. However, some HOCs only weigh about nine pounds but only offer up to two liters per minute. In addition, some HOCs are light enough to move around your home, and some have wheels to help you roll them around. If you're looking for a HOC that is lightweight and portable in your home, consider your oxygen requirements while comparing size, weight, and portability.

Noise Level

HOCs draw in surrounding air, filtering it and removing other gases, which can be noisy. If this noise bothers you during sleep, consider looking for a quieter machine. HOCs usually run between 40 and 60 decibels, so look for a unit as close to 40 decibels as possible. For context, 40 decibels is about as loud as birds chirping or the sound of being in a library, and 60 decibels is about as loud as a running air conditioner or a close conversation.

Humidification

Supplemental oxygen can dry out your nose, especially if worn around the clock. Humidification helps relieve this problem, but not all HOCs offer this feature. If you’re on a higher flow of oxygen, wear oxygen 24/7, or have concerns about a dry nose, consider an HOC with humidification available.

Warranty

HOCs are meant to last long, so consider a warranty before purchasing. Many warranties are three years, but manufacturers offer different warranties. Without one, you'll rely on the manufacturer's trustworthiness to stand behind their claims.

How to Purchase a Home Concentrator

Here is a quick checklist to start the process of choosing a home concentrator:

  • To start, find the liter flow that was prescribed by your doctor and narrow your search to the concentrators that will meet your oxygen needs.
  • Next, sort by size and energy consumption, as well as other specifications in the concentrators that are within your budget and financing abilities.
  • Finally, once you find a concentrator you like, begin the process of verifying your prescription and insurance, and request pricing information for further comparison.

Advantages and Disadvantages of HOCs

Some advantages of HOCs include:

  • HOCs offer higher oxygen outputs than smaller, portable units, making them suitable for those with higher oxygen demands. Some HOCs deliver up to 10 lpm, while some POCs deliver up to only 3 LPM.
  • HOCs allow you to wear oxygen at home, and some units are small enough to move around inside your house.
  • Since HOCs utilize room air, you don't need to worry about them running out of oxygen, unlike oxygen tanks.
  • HOCs continue working while connected to a power source.
  • HOCs are an excellent option for those who require continuous oxygen during sleep.
  • HOCs can be used with a nasal cannula or a mask.
  • HOCs are compatible to work with CPAP machines.
  • Humidifier bottle can be attached to all HOCs since they provide continuous flow oxygen.

Disadvantages of HOCs include:

  • HOCs are generally stationary and not portable.
  • HOCs are much larger than POCs.
  • HOCs can be noisier than smaller POCs and oxygen tanks.
  • You cannot travel with HOCs.

Is an HOC right for you?

When deciding on the best oxygen delivery method, consider your needs:

  • What is your prescribed oxygen flow?
  • Do you travel frequently?
  • How active are you?
  • Do you require oxygen only while you sleep?
  • Do you require oxygen 24/7?
  • Do you need oxygen while leaving the house to run errands?

If you stay active, frequently travel, and have minimal oxygen requirements, you might consider a portable oxygen concentrator rather than a larger, stationary HOC. However, an HOC might be for you if:

  • You only require supplemental oxygen while you sleep.
  • You have higher oxygen demands (more than 2-3 LPM). Some HOCs deliver up to 10 LPM.
  • You can leave your home without supplemental oxygen.
  • You are a mouth-breather and require continuous flow oxygen.

Tips for setting up your HOC

If you decide that an HOC is the best oxygen delivery method for you, here are some tips to get you started:

  • First, look over your user's manual for specific instructions. Each unit should include one in the box.
  • When setting up your HOC, place it at least one to two feet away from furniture and the wall. This way, it's able to draw in room air effectively.
  • Connect the humidifier if there is one, and then connect the oxygen tubing to the humidifier. Make sure to use distilled water, not tap water, for humidification.
  • Connect your oxygen tubing to the oxygen nozzle if you don't have a humidifier.
  • Check your filter, making sure it's in place.
  • Check the manual to determine how long the machine needs to run before producing sufficient oxygen. Some devices must run 15-20 minutes before the oxygen becomes fully concentrated.

Here at the Oxygen Concentrator Store, you can quickly start the process of purchasing a home concentrator by speaking with an Oxygen Specialist.
