A Portable Air Purifier For Single Room Use - 5 Star Review

Portable Air Purifier - Review

We needed an air purification system for our bedroom that was non-intrusive and effective.

Fortunately for us, our son already had this particular model in his room for several years.

Since we knew the product had been tested, we decided to go ahead and get one for our bedroom.

The RENPHO Hepa Air Purifier Filter Replacement

Before purchasing this item, I asked my son about filter replacement. 

There are two dogs in his room, so it's safe to say that this filter gets a run for its money.

Although you can't wet this filter, he extends the use by cleaning the external dust off of it with a small portable mini-vacuum. 

He doesn't replace the filter very often; he said a few times per year is all. However, he pointed out that his filter gets a good workout because of his dogs. Since the dogs aren't in our bedroom, I expect that replacing the filter will only be once a year for our room - maybe twice.

What I Like About the RENPHO Hepa Air Purifier

  • It's lightweight. It only weighs about 6.5 pounds.
  • It's not very large and sits comfortably on a tabletop surface. 
  • It measures 11 by 5.7 by 11.4 inches.
  • No assembly is required, just remove all the plastic and plug it in.
  • No batteries are required.
  • It has rapid purification refreshing the air 5 times an hour in a room of 103 ft² / 9.6 ㎡, and is made for a room of approximately 206 square feet. Our room is about 300 square feet, and it cleans the air nicely.
  • It has a three-in-one Hepa filtration system capturing 99.97% of airborne contaminants as small as .3 microns (such as pet hair and dander).
  • Has 4 fan speeds.
  • A quiet feature also reduces the fan noise and turns off the light at night.
  • Easy to use. Plug-in set your fan speed, and that's it.
Here's a photo of the filter on our dresser:

We purchased our Hepa Air Filter from Amazon. There's additional detailed information at that link on the Amazon page. 

If you need a compact air filter, personally, I give this product five stars.

  1. This looks like something every bedroom could benefit from! I like how quiet it is, how unobtrusive it is and that it uses HEPA filters. One of these might be on my husband’s and my future!

  2. Why have I never thought of this? We are in the middle of construction on all sides and dust in the air is a constant battle. I'm sure that this little workhorse could take on that job nicely. Thank you for a great solution to my ongoing problem with dusty air! I'm sure putting this on my list of must haves!

  3. I appreciate the tip about cleaning the dust off the outside of the filter to extend life! I wondered if you could do that ❤️

  4. I've never had an air purifier but what an awesome suggestion! I have no doubt we would sleep better. I also don't like the smell in my kitchen the day after I fry anything or cook with onions. I wonder if I need one in my kitchen too. Thanks for the recommendation & review of this awesome air purifier!

  5. My brother had one of these when they had a houseful of one dog and 4 cats and really found it helpful. Thanks for your excellent review, Barbara.

  6. I think it would work well in the kitchen. We have the same problem after cooking certain foods. Sometimes it lasts for a couple of days, this sounds like the perfect solution. Thanks for the recommendation!!

  7. This air purifier sounds great and a very useful item to have especially if you have pets. It's wonderful that no assembly is required and no batteries and it looks very unobtrusive. Thank you for sharing your good experience with this product.
