Allerair 4000 Vocarb

Allerair 4000 Vocarb Review Summary

The Good:
With a very thick carbon filter, this machine is well-equipped to reduce smoke or odor problem.

The Bad:
The design is outdated and the control is manual.

The Bottomline:
If you don’t care about noise, style and ease of use – but need a powerful machine that could help reduce odor, smoke and harmful gases, consider this one. But if you need a balance between the two, look for a Rabbit Air or Alen Corp machine instead.

What we like about the AllerAir 4000 Vocarb

The filters: At a glance, it is just like any other AllerAir air purifier. It has a vacuumable pre-filter, anti-microbial filter, a thick 12 lbs carbon filter and a high grade medical HEPA filter.

But the difference is in the carbon filter. It is a boosted blend, designed to aggressively combat odor, smoke and gases. AllerAir says this unit is best used for newly renovated homes or places with heavy smoke or volatile organic compounds.

360 degrees air intake: The cylindrical shape maximizes airflow through the machine.

Made of Steel: To make sure it is suitable for those with Multiple Chemical Sensitivities (MCS), this machine is made of steel so that it doesn’t react with the air. Most machines in the market are made of plastic.

Long Filter Life: While the pre-filter needs to be changed every 3 months, the Hepa and the carbon lasts 2 to 5 years depending on the level of pollution and how frequent you use the machine.

Extra protection: If you need a machine to control airborne fungus, ask for the AllerAir 4000 with UV protection. And if the vocarb blend is not strong enough, the company also offers a custom carbon blend.

But We are concerned that :

• It’s Quite Loud: The lowest setting is 35dB. If you’re a light sleeper you definitely won’t enjoy having this machine in your bedroom.
  
• Has only 3 fan speeds: You only have the option of  low, fast and turbo.
  
• Heavy : At around 42 lbs, with the help of it’s wheels you may be able to push it around. But forget about lifting it up the stairs if you have back problem or over 50.
  
• Has no digital display: Like Austin Air machines, the control is old-fashioned.
  
• Has no digital features: Because it is not a digitally controlled machine, there’s no remote control, timer or filter replacement alert. You need to remind yourself to change your filter ( which is troublesome, since you need to replace each filter at different time ).
• Looks outdated : Your guests might wonder why you keep a humming log in your home.
