What do I do?

Since 2014 I have been methodically testing products for the home, compiling information, creating reviews, and doing my best to help create exceptionally helpful resources for my readers.

Since I was old enough to start buying my own stuff I have relied on serious and in-depth research to help make informed decisions.

Kayla & Derek from the Modern Castle team

I’ve never been one to make an impulse purchase. When I was 12 I built my first computer. Research at the time was reading through PC magazines, asking employees at the local Micro Center, and discussing with my dad.

As I grew up, so did reviews on the internet. In the last several years seeking out high quality reviews online has been essential to my research for virtually everything I buy.

While there are no shortage of reviews online, so many reviews leave me disappointed or questioning the rationale for a particular review rating.

I created Modern Castle to help change that.

Great reviews start with great testing. I take great pride with designing and executing the tests and experiments for every product I test. Completing specially designed tests provide a level of objective data that helps replace mere subjective opinion with more objectivity and hard facts.

Opinions are wonderful, and you’ll find plenty of those here, but I believe reviews can be better when a combination of compiled specifications, objective data, and subjective analysis are married together.

  1. Hi Derek,
    I purchased the Dyson TP02 for cooling purposes. I read in their manual, “WARNING: This product contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm.” This is a little alarming and debating whether to return it. Is the exposure through daily use or by taking the unit apart?
    Thank you for your time.

    • I did a little research this morning and I wasn’t able to find out what specific prop 65 chemical Dyson is using in the TP02.

      As to whether it’s through daily use or taking the unit apart, they don’t say.

      That said, I don’t know of anything within the TP02 (or any Dyson purifier) that would be harmful from daily use. Like most purifiers, it literally is a fan + a filter. That’s it. There is nothing there that can harm you.

      I would guess one or more of the plastics they use is a carcinogen. So long as you don’t eat / melt / spend lots of time handling that, you’re probably fine. But again, that’s just my best guess.

  2. I had a question about this Acum Cordless Vacuum Review [DC-901] review. This vacuum description states that it has a 4 stage filtration system. Is the vacuum anti allergen sealed like shark vacuums? The HEPA filter doesn’t mean much if the entire system isn’t designed to be sealed. Everything you are vacuumed will just leak out of the vacuum before it reaches the filter. Shark vacuums that are sealed are actually labeled sealed and anti allergen.

    • Yes, it is sealed.

      According to Acum: “Fully sealed design prevents leakage of particles and helps protect the cordless stick vacuum cleaner itself as well as your health.”

  3. Hi! I’m down to selecting either a Molekule Air or a Dyson TP 06. My goal is to capture and destroy mold spores (not filter with HEPA). Both above models claim to do this. Not too concerned about formaldehyde. Any recommendations?

    • If you’re not concerned about formaldehyde there is no reason to spend extra money on the TP06.

      Dyson TP04 (see here – has all the same specs as 06, except for formaldehyde destruction, and it’s notably less expensive.

      Based on our tests, the Dyson TP04 yielded better purification performance compared to Molekule at a lower price point. Molekule arguably looks cooler, but in terms of performance per dollar, I think the Dyson is the better choice.

  4. First, thank you for the great reviews on the Dyson Purifiers, I’m in the market and they help a ton. Have you had a chance to review the TP06? Is the worst the extra $100 to “KILL” formaldehyde vs just trapping it? Is that really the only difference? Any help would be appreciated, thank you!

    • Hey Homer,

      Thanks so much!

      So regarding the TP06, we have a pre-test review up (basically an analysis of the specs and hardware here but we haven’t tested it yet. So please bear that in mind.

      That said, from what we can tell, the TP06 is the same specs and hardware as the TP04, but with the addition of the plate to destroy formalydyde.

      Also to clarify, the TP04 and other non TP06 / HP06 purifiers do NOT trap formaldehyde. The particulates are too small, so they simply pass through the machine. The TP06 and HP06 are the only Dyson purifiers that are able to remove formaldehyde from the air.

      So is it worth it? It really depends on your home. Most homes have fairly low levels of formaldehyde and it’s not an issue. However, some homes have higher levels. If you think you may have higher levels then it’s absolutely worth it as formaldehyde has been tied to a number of studies that show its harmful effects.

      Hope that helps!
