    • A filter material take-up product and a paper winding core, which are free from secondary-contamination by an outgas while being transported or stocked. Irrespective of its application such as building air conditioner, an air cleaner or a semi-conductor factory, the amount of the outgas to be generated from the filter take-up product for the air filter can be kept at a negligible level. The filter take-up product for the air filter is produced by coating and wrapping the filter material for the air filter, as wound on the winding core, with a film wrapping material which is so made of phenolic compounds, carboxylate esters, phosphate ester or cyclic siloxance as to have an outgas generation in an amount of 100 ng/g or less by the dynamic head space method.

    • Compositions, methods and apparatuses for reducing or eliminating malodors from indoor air are described. A method is provided for the reduction or elimination of malodors from indoor air using vapor phase hydrogen peroxide generated from either evaporation from a pH neutral to mildly acidic aqueous-based liquid composition or sublimation from a solid composition containing at least one pH neutral to mildly acidic solid hydrogen peroxide-containing compound. The vapor phase hydrogen peroxide (VPHP) engages a media coated with at least one transitional metal element or compound in the presence of air that contains malodorous compounds. The combination of the vapor phase hydrogen peroxide and the transitional metal compound, which acts as an oxidation catalyst, provides increased efficacy of malodor molecule oxidation. One execution of said apparatus employs a disposable porous non-woven filter pad, coated with one or more transition metal compounds, and a solid source of VPHP also disposed within said apparatus. Malodor-containing air engages the coated filter pad in the presence of the VPHP and the malodorants are effectively oxidized. Preferably, the apparatus incorporates one or more chemical mechanisms involving prominent color change(s) in the presence of VPHP, thus indicating to the user whether the device is functional or depleted of VPHP.
    • 描述了用于减少或消除室内空气恶臭的组合物,方法和装置。 提供了一种用于使用从pH中性至温和酸性水性液体组合物的蒸发产生的气相过氧化氢或从含有至少一个pH中性至弱酸性的固体组合物升华而从室内空气中减少或消除恶臭的方法 固体含过氧化氢的化合物。 气相过氧化氢(VPHP)在含有恶臭化合物的空气存在下,与在至少一种过渡金属元素或化合物上涂覆的介质接合。 用作氧化催化剂的气相过氧化氢和过渡金属化合物的组合提供恶臭分子氧化的增加的功效。 所述装置的一次执行采用涂覆有一种或多种过渡金属化合物的一次性多孔非编织过滤垫,以及也设置在所述装置内的VPHP固体源。 含有Malodor的空气在VPHP存在下与涂覆的过滤垫相接触,恶臭被有效氧化。 优选地,该装置包含一种或多种在VPHP存在下涉及显着颜色变化的化学机制,从而向用户指示该装置是否功能性或耗尽VPHP。
