Using a Dyson big and quiet and it has crackling issues only after 6 months

Reddit IconDylansm8

I’ve had a bunch of air purifiers, including the same Honeywell you have. This is my favourite. [https://www.cleanairkits.com/products/luggables-international-california-and-canada?variant=45663048270124](https://www.cleanairkits.com/products/luggables-international-california-and-canada?variant=45663048270124) I was a bit hesitant too since it requires some assembly, but I like this more than my Dyson Big+Quiet. The main benefits of these are low noise even at max speed, highest airflow and CADR(Clean Air Delivery Rate), low power consumption, and cheap filter replacement cost since it uses standard Merv 13 HVAC filters. I have it set up in the bedroom, very low noise and it moves so much air, more than the Dyson. If the assembly is a deal breaker for you, I would keep an eye out for a refurbished Dyson Big+Quiet, Ive seen them on best buy Canada for $500-$600( open box or refurbished) Another good option that‘s less expensive is the Blueair 211+. My mom has that for her condo and really likes it. My only gripe about it is it has a built in Ionizer you can’t disable. And many people are concerned that Ionizers create ozone, which is apparently unhealthy. But its definitely a nice looking unit In my opinion

The Dyson big and Quiet is very stylish and performs very well. Quite expensive though

Low airflow for the high price. With the exception of the Dyson Big+Quiet, which is excellent, although very expensive.

This is just false. Big & Quiet can easily clean even moderate to large rooms. It’s not like the inefficient tower models

How is this applicable to the big and quiet which passes all the air through the filters

I know that to be true for their other models. But the Big & Quiet seems to be pretty good, albeit overpriced (though they are already 40% off in some regions).

Yes! I have severe hay fever and 2 indoor cats, I did get the Dyson big and quiet and that one really cleans the air very well, cooking smells are gone within an hour and it also moves the clean air away from the device instead of pushing it up and creating a very local air circle. Do look for the amount of m2 space it’s rated and what filters it use. Also don’t use a purifier after renovations… you will clog the filters

If you have the money then go for the Big & Quiet! Otherwise the hushjet mini purifier works great in bedrooms!

I have the big Dyson for the living room and the small one for the bedroom. Absolutely makes a difference for us. Look at the comparisons and reviews (the big one is tops in its ability to filter out decent sized areas quickly). We keep them running 24/7

Congrats! Is the whistling wind or motor noise? Try reseating the filters and see. I didn’t observe any unsatisfactory noises on the unit I played with. I hate to say it but if it persists it might be defective. I’ve received multiple big and quiet’s with motor noises right out of the box unfortunately.
