  1. Air purifier real life review.

    Tosot KJ350G vs Winix 5500-2
    Since my request to review of the Winix 5500-2 and the comparison to the Tosot KJ350G
    That are priced the same at around $160, I bought them both.
    Now, this is just my personal early assessment.
    But, I had two of them in a 300 sqf joint leaving dining room area.
    And then in around 400 sqf Master bedroom for a week in rotation.
    We feel that the Tosot KJ350G is a clear winner with his H13 true HEPA filter.
    Tosot KJ350G
    The positive.
    – Tosot was much better in eliminating allergens from the air comparably.
    – Tosot carbon filter dose a great job in eliminating odors as well.
    – Tosot Auto function worked better in comparison.
    The negative.
    – No remote.
    – Not washable pre / carbon filters.
    – Location of handheld on two sides required 2 hands handling (heavier)
    – feels noisier comparably in lower fan speeds.
    Winix 5500-2
    The positive.
    -Winix looks a bit better.
    – Winix have stronger fan.
    – A remote.
    – Washable pre / carbon filters.
    – Location of handheld center top single hands handling possible.(lighter)
    -feels quieter comparably in lower fan speeds.

    The negative
    – The Winix carbon filter is not that affective in removing odors its have palette based carbon filter not fiber.
    – We felt that the Winix HEPA filter doesn’t remove all of the allergens from the air.
    – Winix Auto mode is a bit wacky.
    Similarities
    – The plasma wave feature of the Winix is like the Tosot UV feature, No one can really tell how helpful and effective it really is.
    – Both units are Energy Star rated.
    – both units filter replacement cost is same, around $40
    Please shoot me an email when you do the review and compression of this two units.
    Looking forward to seeing that.
    Thanks David.
    Disclaimer
    This was a real life feel test of the units.

    • Thanks for sharing your experience, David. This is super helpful!

      We’re currently testing the Winix 5500-2 and I expect we’ll publish that review later this week.

  2. Looking on all your air purifiers reviews you missing important and very popular review of the Winix 5500-2 and if you can compare it with the other solid Tosot KJ350G purifier will be great.
    Thanks

    • Thanks, David. We’ve received quite a few requests for Winix. So I am going to go ahead and order that one now.

      We’ll have a test and review up in a couple of weeks.

  3. Hi! Great review and well done. I’m looking at the Levoit Core 300, Germ Guardian AC4825E and Molekule mini & Mini plus. Other than air purifying, which one would be best for my smell as well. Thank you

    • None of them are going to be miracle workers in terms of smells. However, the Levoit Core 300 should be the best among these 3.

      It has the largest carbon filter, which is the essential filter to best remove offensive smells and odors.

  5. I’ve used your website in the past with help picking a vacuum and air purifier. I’m now in need of a humidifier but I’m not sure you review them. Just a suggestion and thanks for all the help in the past!

    • Hey Joshua,

      We’ve tested a few humidifiers in the past, but nothing that was an incredible stand out.

      Honestly, we didn’t see much interest in humidifier reviews so we stopped doing them.

      While we haven’t tested their humidifiers, we have tested a ton of Levoit air purifiers. We’ve found them to be among the very best value air purifiers on the market. I fully expect their humidifiers would be a similar value / performance level. I’d suggest taking a look at those first.
